While Hermes is messenger of Zeus, Iris is messenger to Hera.
There were two: Hermes a herald of Zeus. Iris, a messenger of Hera.
Don't forget Iris. -Indiriel ---------------- Hermes
Iris was also a messenger along with Hermes, so I believe that she could...

Since you placed this in the Greek Mythology forum, I'll assume you meant the Messenger of the Gods. Hermes and Iris were the messengers of the gods, with Hermes usually acting on behalf of Zeus, and Iris on behalf of Hera. Iris had no Roman counterpart, but Hermes' was Mercury. They had no successors.
Iris and Hermes were both immortal messengers.
No. That was Hermes's job.
The name of Zeus' messenger was Hermes. He was also the god of travelers, merchants, and thieves in Greek mythology.
Iris was the goddess of the rainbow. She often worked for Hera as Hermes worked for Zeus.
