#1 Leave. My pride is not worth someones life.
#2 Leave if able, OC if not, see #1
#3 Leave if able, but multiple attackers does change the issue somewhat, I've seen some pretty bad beatings my indviduals much less a gang. If they are obviously intent on serious bodily harm and there are potential weapons around (sticks pipes things of that nature) then I would probably draw my weapon but would only fire if they continued to close.
