I want to use jitsi with my new buisness. Checking to see if it has everything I need

Hi there, I have a bunch of questions.
Can I invite up to 100 people to a group setting?
Can they mute and unmute themselfs?
Does their name show up on the screen?
Is there a chat option for discussions during class?
Do I have the ability to share screens?
Is there a way to show a raised hand icon?
Ok, I’m just going to start with these?
Thank you so much for any information.

Yes, and you can go to meet.jit.si and try it yourself.
