4 Coins of mystery to me. Hoping the experience here can help

The first coin is the back side of a ancient? Coin. Picture is better than in before posting. Still haven't got an ID? Thanks!
2nd coin is a fairly large coin, size between Dollar and .50$ cent piece. Hole is a ? But looks like a drilled hole, too bad? Really hard to see any writing but the picture/ standing might be recognizable, to some, experience. Pretty sure it's Europe somewhere and fairly old.
3rd coin is another Europe type coin I think? It a good size too the Picture Head figure looks like one of those Royal rulers a few centuries ago?
4 coin is a very small coin and hard to see with a 5 on it and 1865date? It look like? Can't figure the origin and currency amount compared to the times? Guess the kept kissing the small coins and quite making them? Thank you all for any help with coins, mystery to me at this time!
