Well, good luck - you may need it!
The London one at center at least offers the possibility of a less common reverse (seems to be PLN with star left or right).
I'm guessing bottom right is a Trier Sarmatia.
The top Lyons one is most likely Sol, but Marti or Prinicipi would be nice.
The smaller one to right of center is stumping me ... looks vaguely western c.316 AD. Based on the short legend could be London, but style doesn't seem right. What are you guessing ?
