A few I recall from going to games many moons ago:
Ace - booted from the kennel after serious allegations were made by quite a few (trusted people with no reason to lie). Not sure if they were ever proven, but from memory the club terminated his membership and banned him for life.
Anna & Co (Tina?) - always seen amongst the crowd, and handing out home made food and lollies to people.
Ali & Hansta - leading the chants and heckling.
Captain Kickass - absolute legend of a bloke!
Will.I.Am - another top bloke!
Ferrett and his mate (whose name escapes me now) - Funny as hell guys, with some hilarious heckling moments.
Rami - Was always amongst the crowd chanting!
??? - that young guy that used to absolutely piss off all other fans (and I think Bulldogs fans as well), by running around the stadium trolling opposing fans areas. Pretty sure he got banned from a few stadiums. I recall one day when Canberra was playing us at Accor Stadium he ran amongst the Canberra fans for a group photo.
??? - I can't recall his name, but he always used to clap back at opposing supporters. I recall one game many moons ago at SFS he went upstairs to where a morbidly obese Roosters supporter was and gave the bloke hell until the guy got kicked out.
??? - The guy whose daughter was a cheerleader for quite some time. Always willing to have a chat and laugh.
