Need Help Identifying These 3 Coins

[Count Boris]

My Son was given these three coins from a friend. Not sure what is front or back, or up or down. My first guess is their middle eastern. Any help Identifying, or value. Would much be appreciated.
Thanks Count Boris

Identifying three coins--Count

Count:
Wild guess without doing further research:
First coin: Mamluk (Egyptian)
Second coin: Abbasid Caliphate; (called a dirham)
Third coin: look up Qarlughids and Ghorid coins (note: no "u" after Q)

If you want to read that middle coin, turn it 180 degrees so that the letters start to look like: "XL..." instead of "X7". It then reads:'There is no diety except (the one) God alone. He has no equal."
