Is a camel statue good to keep in the house?
This is a subject of astro vastu. Different items represent different planets; if a planet is very negative in your kundli and you keep the item that represents it, the negativity grows further. Which item suits which home, and with what, is covered in interior vastu.

What is the difference between the lagna kundali and the KP chart, and which is used for interiors?
Use only the lagna (birth) kundali for interiors. The KP chart is based on nakshatras and is not bad, but there is no need to debate it here.
As an interior designer, clients choose their own colours and I cannot check their planets; should I give a remedy or try to convince them?
Do not try to convince anyone. People mostly like the colours that match their own planets. If a client chooses an anti-element colour and their kundli allows it, never stop them; it will bring them benefit.
Besides exaltation, debilitation and degree, how do we judge whether a planet is good or bad, for example in the 6th or 8th house?
The 6th and 8th house rule has not been given yet. The full rules will be taught later using example kundalis of five students. For now judge by exaltation and debilitation; not every 8th-house placement is bad.
Can a person whose Sun is debilitated (neech) have the drawing room in the East?
Yes, with remedies; he will not leave the East unused or build a toilet there. A drawing room is not a permanent seat. Only permanent seating, such as an 8-hour business seat, should not be chosen in the zone of a debilitated planet.
Can these planet artifacts be used even when the birth chart shows no defect?
Yes. Without a dosh they simply add energy. Nobody would refuse if God offered an exalted Jupiter, Mars or Saturn in their chart, and decorating with the items that represent such planets raises energy in the same way. Energy never becomes so much that it causes harm; how the gain is used is the person's own responsibility.
Do the directions of the kundli houses shift when the rashis or planets in them change?
No. The 4th house is always North, the 1st East, the 10th South and the 7th West, with the sub-directions between them. Like water flowing in a river, planets and rashis keep moving, but the direction a house represents stays fixed whichever planet or rashi comes into it.
