№ 1. I think this coin was released in the middle of III century. But I don't know the name of emperor.
№ 5. My guess: the second half of the IV century or the beginning of V century. Honorius (395-423)? Arcadius (395-408)? Theodossius I (379-395)? Theodossius II (408-450)?
The woman is Faustina II or, less likely, her daughter Lucilla or daughter-in-law Crispina, all of whom had the same hairstyle. The goddess on the reverse is Tyche (Fortuna).
