The first coin is Constantius II with a FEL TEMP REPARATIO reverse. The mintmark is not clear and I can't see any field marks on the reverse; so it is tough to be specific...maybe from Siscia. You are right that the second is Licinius I -- Licinius I A.D. 317-320 IMP LICINIVS AVG- laureate and draped bust left holding mappa, orb & scepter. IOVI CONSERVATORI AVGG- Jupiter standing left with Victory on a globe & sceptre, wreath left, Δ right. In SMK RIC VII Cyzicus 9
