Help id this lot of ancients

[Amarmur]

I bought a lot of ancients and I need help identifying them. 

I believe the Greek coin has Zeus on it.

The roman one is Constantine the great era with vows. 

The third is a complete mystery to me. Islamic?

Thanks so much!

oh no not another Constantinius II... Every ancient coin lot is littered with them. I'm selling this one (not like I have many buyers) It will probably go for like $5.

I think it might be Constans. From an eastern mint.

Clue # 2 : I believe only seven Emperors had this reverse ( but I could be wrong):

Constantine the Great

Constantius II

Constans

Valens

Valentinian II

Gratian

Arcadius
