Roman bronze coins, 18-20mm

Unable to find these three on Numista, or reliably identify them. The information on each of the images is largely speculative. Any help would be much appreciated.

Nb#2 : Yours is in a better shape
Nb#3 : Constantinus PROVIDENTIAE CAESS

Coin #2: https://en.numista.com/catalogue/pieces107385.html
I can easily read ...CTORINVS, so it was easy to go on Victorinus to search.

Coin #3: https://en.numista.com/catalogue/pieces86654.html
I was able to read CONSTANTINVS IVN (Constantine Junior), and the Antioch mintmark (SMANT) was easy to read.

About # 1 sorry but I have no clue (near zero experience with greek ancients).

​Thanks for that. I'm a beginner at this (and feel a bit silly that I couldn't find them).

Thanks for your help, I've not yet found my way around with ancient coins!
