1. Is there a limit to the time that Brook can remain outside of his body in Soul Mood?

the laws of nature tell me that there must be (how about 100 years max)

2 If Brook is in Soul Mood, can he enter or travel underwater?

No he can't travel in water, he travel's above it or below it in the ground but not in it, this is actually seen in the flashback of his soul looking for his body

3. Brook's soul ability lets him go threw walls but is possible for him to touch or feel anything? like opening the door from other side or pushing a button.

He can go through everything but water or kairoseki, he still feels things like cold, heat, smell things, hear things, talk etc. but since he is intangible he cannot open doors or cages, he however can float through them so there is no need for him to open them.

4. Is there a limit to how far can Brook travel in his Soul Mood from where his bone-body is located?

The limit is the sky or space, I am sure he could travel on land, above water and in the sky and under the ground but not in space.

5. If Brook is in his Soul Mood, what will happen if someone places Sea Stone handcuff on his bone-body?

His soul for will be weakened somewhat, he has more diffuculty entering his body or can't enter it at all.

6 Is it possible for Brook's soul to enter and control another person or creature's dead body?

If he is able to control living people it will only be for a very short while 5 minutes at most, however when it comes to dead bodies he might be able to control them anything from several hours till several years, however since the body and the soul are part of the same being they must eventually be reunited.

7. Is it possible for Brook to die? He is a soul to begain with.

Yes everything that is born has to die, yukichi skull is the former eater of the yomi yomi no mi (before brook), he probably lived for a very long time, then died and lived for an even longer time, but the fact that brook now has his devil fruit power means he died.

8. Is it possible for Brook's soul to communicate with other dead people's wandering souls? or wandering souls don't exist?

If there are other souls he can communicate with them.
