Let me see what I can do, most of these coins are in a very bad state.
For #2, the reverse is clearly VOT X. Searching a little more I got something:
Crispus, reverse CAESARVM NOSTRORVM VOT X.
Mintmark is uncertain, not sure of what letter I'm seeing. And the photo is upside down.
For #3, I see at the obverse …NVS PF AVG.
But that itself means almost nothing, lots of emperors end their names in …nus.
For #6, the face is reasonably visible, but no lettering visible.
The reverse with the two soldiers is clearly GLORIA EXERCITVS.
For #7, the obverse is a lost case.
The reverse with two victories rings a bell, the lettering may be VICTORIAE DD AVGG Q NN.
#8 is looking better than the others but I'm not having luck in distinguishing the letters.
