I don't know if you get on well with the other five or not, but you should let them know that it was your idea. At least then there wont be more than one of you upset if this all blows up.

I agree that you should go see someone higher up from this guy. If he really is that bad, then you need to do something about it. Maybe he wont be reprimanded or disciplined because of your complaint, but if every student who has a problem with him makes a complaint, then the uni is eventually going to see a pattern and start to wonder.
