4 late imperial Roman coins

Top left: might be Maximianus, but I am completely confused when I get to this page:

https://www.wildwinds.com/coins/ric/maximianus/i.html

Top right: the text seems to read ..Constantinus… , but which one?

Bottom left: Valen…

The  top left seems to be this one:

Ticinum
RIC VI 31b

Maximianus AE Follis. 296-297 AD. IMP C MAXIMIANVS PF AVG, laureate head right / GENIO POPVLI ROMANI, Genius standing left, holding patera and cornucopiae, star in left field. Mintmark PT.

A bit better images of the remaining 3:
Constan…
Valent…
Constan…

First one (from your last image): https://en.numista.com/catalogue/index.php?e=rome&r=&st=1-2&cat=y&im1=&im2=&ru=119&ie=&ca=3&no=&v=&a=&dg=&i=*soli+invicto+comiti*&b=&m=np&f=&t=&t2=&w=&mt=&u=&g=&c=&wi=&sw=

Constantinus I., SOLI INVICTO COMITI.
The mintmark is at the bottom of the reverse. It should be readable, but you images are still a little bit blurry 🙂. Also there are no marks on the sides of the figure on the reverse, this further narrows things down.

Second one: https://en.numista.com/catalogue/index.php?e=rome&r=&st=1-2&cat=y&im1=&im2=&ru=127&ie=&ca=3&no=&v=&a=&dg=&i=*secvritas*&b=&m=np&f=&t=&t2=&w=&mt=&u=&g=&c=&wi=&sw=

Valentinianus I., SECVRITAS REIPVBLICAE
There are no officina marks around the figure, only the mintmark at the bottom. I'm not sure about that, I think it's maybe SMA_S, the fourth letter is not clear. I suspect that this is the Aquileai mint, that uses similar mintmarks.
 

Thanks a lot. I am still getting experience in Roman coinage, and really appreciate any assistance.

The last one: https://en.numista.com/catalogue/index.php?e=rome&r=&st=1-2&cat=y&im1=&im2=&ru=124&ie=&ca=3&no=&v=&a=&dg=&i=*spes*&b=&m=np&f=&t=&t2=&w=&mt=&u=&g=&c=&wi=&sw=

I think it's Constantius II., SPES REIPVBLICE, but it's in a very rough shape. The mintmark (at the bottom of the reverse) is completely missing.

I tried to locate it here:
https://www.wildwinds.com/coins/ric/constantine/i.html
The mintmark is visibly SARL, not TARL, but none of the images matches mine (namely, all the closest images have letters below Sol's arms, but mine does not).
Could it be a different Constantine?
