No 2 is very low grade but I think I can read "ODO" on the obverse legend which would make it Theodosius I, the reverse is SALVS REIPVBLICAE, SMK (Cyzicus) mintmark.
No 3 is as far as I can tell Constans with a VICTORIAE DD AVGGQ NN reverse, TES (Thessalonica) mintmark. It could also be someone else from the Constantinian dynasty if part of the obverse legend is missing at the top of the coins but as is right now I think it's Constans.
Giobruno took care of no1 and no6, no7 is in my opinion a provincial issue. As for the rest they're also 4th century, very low grade but maybe identifyable. No 4 is minted in Constantinopole (CON mint mark) but I don't recognize the reverse, the emperor's name starts with DN ends with AVG, no 5 has a SALVS REIPVBLICAE reverse.
