My Jupiter is exalted and my door is on N6-N7, towards the North-East, yet we have had no problems. Why?
The Ishaan (North-East) corner belongs to Jupiter, so people whose Jupiter is exalted can keep their door there. This shows how the birth chart decides which door suits a person.
The 5th lord is Mars but the child studies in the West. Is that wrong?
See in which direction the 5th lord sits. If it sits in the West, that is excellent; if in the East, choose the East. The East and North are best for study anyway, and if the lord sits in the South, studying in the South also works.
The kundli chart was shown with directions. How are those directions used, and what can a kundli tell about a house?
Go by the houses, not the numbers written in them: the top house is the 1st house (East) and the 4th house is North. If the planets on the North side are strong, the North direction is very good for the person. A kundli can even reveal where a person's house is, where its door is, how many windows it has and where a nearby river, pond or temple lies, so a map of the house can be drawn without seeing it.
Where should shoes be kept?
Shoes can be kept almost anywhere except pure North, North-East and East.
Where should the kalash, rising sun and lotus painting be placed?
If you need a partition between the North and the East, make this painting on the glass partition there. If you do not want glass, the painting can be made on cloth and hung instead.
A family with an N4 door has had only boys across generations. What can be done for a girl child?
N4, like N3 and W4, is a door that brings sons. Open an E2 door, which brings the birth of daughters. A home without a daughter is not a complete home.
