Help needed identifying these coins please - part 2

part 2
Looking for some help. I’m not sure if these coins are genuine or not. From what I can tell searching around, they look like Roman and Greek coins. I don’t see any obvious WRL markings or the like to signify replicas but I am not sure. 
 

Any guidance would be appreciated. Thanks in advance.

Coin 4  - diameter 29mm, weight 19g

Coin 5-  diameter 28mm, weight 8g

Coin 6 - diameter 30mm, weight 16g

Coins four and six are large bronze coins of the emperor Hadrian.

Thanks for the response. How would I tell if they are genuine?

They seem to be genuine, just severely over cleaned
