Back to the Yomi, IMO the DF ability is still active, allowing Brook to do whatever he wants in soul form (fly away, control bodies, etc.). I think the Yomi's ability is letting the user separate the body and soul which was activated by death. But Brook needs his body for it (his body consumed the DF power after all). Therefore Brook's body is like a horcrux. ;) If the it was destroyed or had handcuffs on, the soul would be uncontrollable. If the event is irreversible, Brook will die this way. Otherwise he stays alive (after the kairoseki is removed).

Here are my answers:

1 No

2 Probably

3 No

4 No

5 The soul would become „inactive” and disappear but respawn when the kairoseki is removed. Same happens when the soul is inside the body.

6 Probably

7 Yes

8 If they exist, yes
