Last one looks like Gallienus
GENIVS AVG with
V in left field and
I in right.
I don't think yours is in RIC, RIC 5a 197 and 198 are the two closest but 197 has a 'from rear' bust with a shield and spear and 198 has 'IMP' at start of obverse legend.
Here is the same coin from Beast coins with their description of the problems assigning it to RIC:

Gallienus, AR Antoninianus, 260-268, Sole Reign, Rome
GALLIENVS AVG - Radiate, cuirassed bust right
GENIVS AVG - Genius standing facing, head left, nude but for chlamys over left shoulder, patera in right hand, cornucopiae in left, ensign at right
V |
I across fields, 23mm x 25mm, 4.85g, RIC V, Part I, -- (cf. RIC 197); Göbl 372x
Note: RIC does not list this combination of obverse legend and fields marks. Also, the reverse is of extremely unusual style and the lettering on the obverse and reverse dies must have been engraved by different celators.
