Ancient Coins - Help Identify Part 3

#1: Byzantine: late follis, "anonymous" type with Christ on the obverse and Christ's titles on the reverse, something like this one.

#2: Late Roman: Constantius II, reverse type FEL TEMP REPARATIO (happy times restored) with a soldier spearing a horseman, mintmark looks like ANZ - Antioch mint, officina zeta (7). This example is officia alpha but otherwise identical.

#3: Middle Roman: an antoninianus or "radiate" commemorating the deceased emperor Claudius II, reverse an Imperial Eagle with CONSECRATIO around. Example.

#4: Late Roman: Constans, a different FEL TEMP REPARATIO type, this one with a soldier removing someone from a hut. the mint might be Antioch again but there's not quite enough of the mintmark lettering left to read.

#5: Late Roman: Constantine I, reverse a "campgate", PROVIDENTIAE CAESS (to the providence of the caesars). I really can;t tell the mintmark on this one.
