Цитата: "Cycnos"Hello !
I agree about the first one.
You are right about the mint of the second one (Novar) too, minted under Bayezid II (886 AH) : https://en.numista.com/catalogue/pieces109094.html
Last one I tend to say Crimea as well with the tamgha on the first picture, but I must admit I can't help you out with it
The last one may be Dihram of Mengu Timur (Golden horde), Bulghar mint.
Something like this: https://www.zeno.ru/showphoto.php?photo=38871 but heavily cut under the later weight standards
First picture shall be rotated about 90 degree left
Second - ~170 right
There is a date 67? - you can try to search on Zeno with it
My personal list of scammers from Numista: erniemix, yvain, CassTaylor
Hmmm... I couldn't match it with this coin : the script is too different.
With your orientation, I see kuffic inscriptions badly written on both sides... it could match with a contemporary imitation of a mamluk half dirham (under Shaykh rule ?) : https://www.zeno.ru/showgallery.php?cat=4840
