Puzzling with 4 Crimean coins [επιλυμένο]

I'm trying to figure out my Crimean coins, but I can't say I'm making any progress, so I thought I should turn to the experts for some guidance.

I have four coins infront of me which I cannot figure out (and they might not even be in the catalogue yet, which makes it even trickier for me). I wasn't sure if I should give each coin its own thread, but I decided to out them all together.

Please keep in mind that some photos might gave to be rotated, since some coins too worn to make out the script, but if you know the coin it's easier to find its right rotation.

Coin 1: Arslan I

~15 mm
~0.6 gr

Coin 2: Mehmed II

~9 mm
~0.5 gr

Coin 3: Dewlet I (or Davlat I)

~13 mm
~0.6 gr

Coin 4: Sakhib I (or Sahib I)

~14 mm
~0.5 gr

Any feedback, ideas, and facts are welcome.

Cheers!

There are plenty of subtypes which may be found in the catalog of Retovskiy

​Awesome, tvanks a lot!
I have been looking at all these listings, but wasn't too sure.

Accordng to № 3, I do see the year 957 very clearly, but since it was upside down (to get the insignia turned the right way) I wasn't sure if it was the date or not.
