That's called the challenge flag, each coach gets to throw that flag in their sock in order to signal to the refs that they disagree with the call on the field and would like them to take another, closer, look at the play. If the challenge succeeds, the play is reversed. If the challenge fails, the coach loses a timeout. If the team has no more time outs then they cannot challenge a play.

Yes......."too many men on the field" is reviewable. And if you watched Superbowl XLII you would have seen it done.
The coach on either team can throw a "red" challenge flag if they feel that the ref's call on the field is in error.This goes for defense or offense. If the call is reversed to in fact be in favor of the challenging coach, then the ref's decision on the field is overruled and there is no further action. If the call on the field stands (does not reverse due to the challenge of the coach), then the challenging coach is charged a timeout. A coach is only allowed two challenges per half of a football game.
