If this were based on a factual basis then Jackie Chan would win with ease and why you ask?
Bruce Lee - Was in over a hundred actual street fights and won most of them. sadly he's dead so he'd be easy to beat. If he were alive he would have won though.
Jackie Chan - Is a performer and a choreographer but can hold his own in a fight(back in the day anyway). It would probably be him versus Norris and i'd say Chan would win against Norris because despite his age he's still more active.
Jet Li - Is a performer and athlete he's never really claimed to be a street fighter so I don't know. He could maybe stand around looking cool.
Chuck Norris - Is super christian now, wouldn't hurt a fly.
Superman - Is a fictional character.
Stan Lee - Is some old enthusiastic guy.
So yeah I guess Chan would win but if Lee were alive then he would win, no doubt.
