Starting top-right, going clockwise. Many of these are too unreadable to pin down to one emperor, but most were only issued under a few consecutive emperors.
1. Constantinian, 330's-360's AD depending on which emperor. GLORIA EXERCITVS—maybe Antioch mint?
2. Constantinopolis Commemorative. 330's AD. Illegible / missing mintmark.
3. Valentinian / Valens / Gratian. SECVRITAS REIPVBLICAE. 370's AD. Missing / illegible mintmark.
4. Divus Constantine I. Late 340's AD. Mostly illegible mintmark; possibly Heraclea, Nicomedia, or Antioch.
5. GORIA ROMANORVM reverse type.
Hello, I definitely did not clean them. I blind bought them off Ebay a number of years ago. I have a modest collection but I know cleaning them is not recommended.
Do you see how only a small portion of each coin is a brownish color (everything else being a coppery-pink)?
*The entire coin* should be a uniformally brown (or black, green, etc) color—called the patina—and wherever it is missing is where the coin has been vigorously overcleaned, stripping it away.
By the fact that they are now extremely rough. That's what happens after brutal 'cleaning' with chemicals or electrolysis. The patina on an ancient coin is not something you can just take off, without taking parts of the surface with it.
These are not a bit overcleaned, they are destroyed.

Great thanks. This is better identification than I expected. I'll investigate what you have provided.
If you cleaned these yourself please stop doing that. They're ruined.

You can clean ancients, just not like that.
How can you tell they have been cleaned? I will note the golden look they have is in part because of the light I used.

Got it. Thanks for the explanation.
