So, lets see what Jupiter can do in 5th house without any conjunction or aspect from any other planet. 1st lets see what these 2 things represent -
Jupiter is the most benefic planet and it represents all the auspicious things like Knowledge, Wisdom, Law, Guru, Spirituality, Religion, Philosophy, Literature, Elderly People. For a girl, Jupiter also represents Husband.
5th house represents Creativity, Happiness, Hobbies, Children, Innovation, Sports, Movies, Stock Trading, Gambling and Betting, Education, Ancient Texts etc.
This person is all about knowledge and education. As 5th house is knowledge and education, Jupiter also represents knowledge and wisdom and Jupiter is the natural significator of 5th house. So, this person is always looking to complete his Degree, Post Grad Degree and higher learnings. They would even travel to the farthest places in the world to gain knowledge. They will gain association of highly enlightened Gurus and later in life, they want to impart the same knowledge and wisdom to their children.
From 5th house, Jupiter aspects the 9th house of higher learnings. So, apart from the normal academic learnings, they will be interested in Philosophy, Literature and reading of Ancient Texts. Teachings of their Guru and Father become highly important to them.
Jupiter's next aspect goes to 11th house of network circles and friends, Here, Jupiter blesses the person with knowledgeable and wise friends, who help him gain in life.
Jupiter's last aspect goes to 1st house/Ascendant of life force and personality. Here, the person is seen in society as highly learned, wise and intellectual person.
Hope this helps. Next - Jupiter in 6th house.
