A few coins [επιλυμένο]

Hello! I need help identifying these coins, it's a little tricky as my dad bought them for me while in the UK so I don't have the most clear images. I do not have weight not diameter (sorry) I apologise for posting 2 types of coins in the same post I am aware it's against the guidelines however I didn't want to put several posts on the forum.

Here are the coins, thank you all in advance

Liban is French for Lebanon.

The last one is Ethiopia

Thank you! Would you happen to know how I found out the dates?

Ethiopia has only one date for that denomination

N#4391

The other 3 are all the same date.

N#11267

Thank you!
