Mr. Radhe Shyam
In astrology houses and signs are different. Signs are the equal divisions in the zodiac. Houses are the imaginative divisions as done by Placidus system in KP, Sripathi system in Vedic astrology. Houses give us the required matters.
In your case Moon is in the 3rd house which is a 4th sign.In 4th sign Scorpio 4th house started at 25°43’42” whereas Moon is in 16°29’27’. It means that Moon is in 3rd house, but in 4th sign from 1st house not from Aries. Moon gives 3rd house matters only with the capacity of sitting in 4th sign. 4th sign is Scorpio which is a watery sign. It gives you envious nature apart from imagination and intelligence.
Likewise other planets you asked me. Saturn is the lord of 6th house and is in 9th house in 10th sign. Observe the degrees of Saturn and 10th house. It is behind 10th house.
You youngsters are not reading astrology, but going through computer softwares, mislead by them and asking these questions. Good. Please learn astrology through good books.
Good Luck
