Welcome to CCF! Coin 1 is of a Valentinian, presumably Valentinian I, who ruled the West from 364-375. Coin 2 is a "Securitas Reipublicae" minted in Siscia in the reign of the Eastern Emperor Valens (r. 364-378). I can't read the text on the obverse of the third but it is a tetrarchic-era bronze, dating from 293 to 324. Hope this helps!
