I know nothing about ancient coins, but I can tell you Number 14 is not from antiquity, but is a French Double Tournois from 1640, from the principality of Orange-Nassau: https://en.numista.com/catalogue/pieces56244.html
Hello,
I can give you some help :
1 is a tetradrachm struck in Alexandria (Egypt) under Roman rule, during 3rd century, with Tyche on reverse. It could be several emperors depending on the legends. Maybe Diocletian.
2 : no clue
3 : GLORIA EXERCITVS reverse type, probably under Constantine I. The mintmark under the feet of the soldiers should give you the location of the mint. I can't read it on the pics.
6 : byzantine follis
7 : same as one, but with different reverse. L B so year two of the reign.
