Channels and admins

I've got a few questions about admins and who can do what.

The Fabric network is just a collection of members sharing the load. I wonder if that could lead to conflicts, as in who is really the boss in a channel. 

Can every organisation in a channel add or kick a member?
Can a channel have multiple admins by multiple organisations?
Can a admin just add anyone to a channel?

Hope someone can make this a bit more clear. Maybe I'm overthinking this stuff.
Still a little new to Fabric myself, so take my answers with a grain of salt...

This depends on what permissions the organisation has been given.

Hopefully someone else can come in and give some more detailed answers.
