Ottoman Coins - Identification Needed

[Panayiotis]

Anyone here has experience in Ottoman coins? Amongst others during 2008 I have bought 3 coins and while searching my transactions they were for : (1 from Abdul Hamid I, 1 from Selim III, and 1 from Ahmed III) probably zolotas or 2 zolotas. Please find below the photos if anyone can help me identify which is which and whether my purchases were correct.

Thanking you in advance ...

Those are some nice coins! Not necessarily in condition, but in coolness and age and rarity!
