I'm also wondering how aogiri tree was created, I'm pretty sure it was hard to invite members and it has to be done forcefully I think but we may get infos on that when it's tatara arc/ aogiri arc.

Probably not, it could only be :re crew but there could be chances that a group or someone will interfere or join the battle between CCG and the Aogiri tree but no one's side.
