Is this legal??

Contraty to popular opinion, exposing your cards IS NOT illegal. It is against poker ethics and can get you tossed from some casinos and home games, but there is no rule stating that this action is illegal. The only restriction is that if you do, you must show all players at the table your cards, this way everybody at the table benefits from the same information. ( and NO, just because I am a little more informed than most DOES NOT mean I do this!)

In every Casino I've played in an exposed hand before the showdown is considered dead. Not sure what you mean by illegal though, It's a home game right. Decide on a rule and stick to it 100%.

Make a rule and then don't invite him back. Yes it's legal but it's bad form.

No rules say you can't. If a card or cards or shown by mistake while being mucked, All players must see them.

Now if someone does it on purpose, the hand is dead. You can also get hurt in the back room if you do it all the time.
