So, let's see how different planets will behave differently as 4th house Lord in 1st house.

Sun - Suppose it is a Taurus Ascendant chart and Sun rules the 4th house with Leo sign and sits in the 1st house in the sign of Taurus. It shows that native has a sense of pride and ego when he talks about his home/mother. Mother becomes a Father Figure for native as house of Mother is ruled by a planet which represents Father. Although, as Sun is not in its friendly sign position, it may show some frustration in relations with Mother. It also shows that you may gain your authority among people of homeland, so it is good for political career.

Moon - So it is Aries Ascendant Chart and Moon rules the 4th house with Cancer sign and sits in 1st house in Aries. Here it shows a person who is emotionally attached to his mother and home. This person is very emotional and caring and want to take care of home and mother. At the same time, Moon is in Aries sign, which gives a very action oriented mindset and these people come with an initiating and aggressive mindset. Here, relations with Mother will be better as Moon is in friendly sign.

Mars - Mars can be 4th house ruler through its two signs. So, let's take both one after the other.

Capricorn Ascendant - So if it is Capricorn Ascendant, Mars rules 4th & 11th house and sits in 1st house in Capricorn sign, where it is exalted. These are real protectors of home and homeland. It is very easy to see them in Police or Army. Mars in 1st house exalted also shows a great inclination towards Real Estate. These guys will have good relation with Mother but as it is a malefic planet, it shows that Mother was also equally aggressive in dealing with native which made them rough and tough in life.

Leo Ascendant - Now if it is Leo Ascendant, Mars rules 4th & 9th house and sits in 1st house in Leo sign. Almost all the things told above can be seen from this position too as Mars is in a friendly sign. As Leo is sign of Government, these people may be inclined towards serving Govt. Both positions can make a person Athlete too. Additionally, as 4th house is ruled by Scorpio sign, it shows some turbulent times in mother's life and native's early childhood.

Mercury - Mercury also can be 4th house ruler through its two signs. So, let's take both one after the other.

Pisces Ascendant - If it is Pisces Ascendant, Mercury rules 4th & 7th houses and sits in 1st house in Pisces, where it is debilitated. It shows a person who is highly imaginative and philosophical in his thinking & approach and mother had a great contribution in making him like that. These people can be writers in Spiritual, Fictional field. Here, communications with Mother may suffer, means it is like either native is not understanding mother's point of view or vice-versa.

Gemini Ascendant - If it is Gemini Ascendant, then Mercury rules 4th & 1st house and sits in 1st house in Gemini. This is much better position then earlier one as Mercury is in own sign. It shows mother had taught the native the art of communication and business. This person can be smart businessman and knows the art of selling. He can be great in communication field too and will do well in fields like writing and journalism. These people are also very clever.

Venus - Venus also can be 4th house ruler through its two signs. So, let's take both one after the other.

Aquarius Ascendant - If it is Aquarius Ascendant, Venus rules 4th & 9th house and sits in 1st house in Aquarius sign. First of all it gives a very pleasant and beautiful personality. This person shares a beautiful relation with mother. They identify themselves with their mother and home, hence they take extra care of home/mother. They can be seen in professions like interior designers. This position gives them wealth from mother or mother-side relatives.

Cancer Ascendant - If it is Cancer Ascendant, Venus rules 4th & 11th house and sits in 1st house in Cancer. This also shows the things narrated above. Additionally, this person is very caring. Service and Devotion becomes traits of personality. They want to take care of their mother and home like anything but at the same time, as Venus is not in a friendly sign, it shows that person is not satisfied with condition of home & mother and wish to make a change.

Jupiter - Jupiter also can be 4th house ruler through its two signs. So, let's take both one after the other.

Virgo Ascendant - If it is Virgo Ascendant, Jupiter rules 4th & 7th house and sits in 1st house in Virgo Sign. It shows that person got some highly religious, morale and philosophical teachings from mother. His mother and home environment was the base behind his knowledge and values. As Jupiter is not in a friendly sign, it shows not much satisfaction from condition of mother or home. This also shows person is very analytical, critical and perfectionist. Here relations with mother are not too good or too bad either.

Sagittarius Ascendant - If it is Sagittarius Ascendant, Jupiter rules 4th & 1st house and sits in 1st house in Sagittarius. From all the positions we discussed, I would consider this one as best because most benefic planet Jupiter is ruling 4th house and sits in 1st house in its own sign. This shows a native who got all the right spiritual teachings from mother. Shows home environment is spiritual too. It shows mother gave such high spiritual teachings that person is almost a Guru to others now. It shows wealth coming from mother or person inheriting mother's property.

Saturn - Saturn also can be 4th house ruler through its two signs.

In either sign (Capricorn/Aquarius) as 4th house lord, Saturn in 1st house (for Libra/Scorpio Ascendants respectively) shows that person will have to go through lots of hardships in his life path. He will get success only when he puts his best effort. Normally, they get success only after mid 30s. It shows that person is getting responsibility or duty of mother/home. Saturn in Libra is exalted, so it may reduce the impact by 5% but nothing more than that. It shows that person had to do lots of hard work and go through lots of hurdles to gain anything from mother/home. It shows a kind of stress in relation with mother. It makes a person self critical. In some cases, person will feel like responsibilities of mother/home are like burden. Saturn in Scorpio may bring turbulent and transformative events to mother. Saturn in 1st house gives a sleek personality.

Rahu - If Rahu is 4th house Lord through its sign Aquarius, as it co-rules Aquarius along with Saturn, and sits in 1st house in Scorpio then 1st of all we need to make sure of Saturn's position as it is the main ruler. Rahu in Scorpio in 1st house shows a person who has gone through lots of transformative events in his life path. Scorpio is sign of Chaos and Rahu explode things, so this person's life path will always be full of chaotic events. Benefic aspects will neutralize the impact. It shows person who is obsessed about research in occult and may even follow occult as life path. It also shows a person who spreads lots of illusion about himself, like you can never be sure about this person. He will have such secretive and mystical personality.

Ketu - Likewise, If Ketu is 4th house Lord through its sign Scorpio, as it co-rules Scorpio along with Mars, and sits in 1st house in Leo then 1st of all we need to make sure of Mars' position as it is the main ruler. As Ketu isolates/separates a person from the things related to the house Ketu is sitting, here it actually separates person from himself, which means these people have lack of self-value or self-worth. They feel that other people are more blessed than them. As Ketu is in Leo, they feel disconnected from people in authority and never show off their authority either.
