What is "pelagon"

There are several figures named Pelagon (Πελάγων, -όνος) in Greek mythology.

1. Pelagon (son of Amphidamas), the king of Phocis who gave Cadmus the cow that was to guide him to Boeotia.
2. Pelagon or Pelegon, who is given in the Iliad as the father of the Paeonian warrior Asteropaeus, son of the river-god Axius and Periboea, the daughter of Acessamenus. Presumably this Pelagon was the eponymous founder of Pelagonia.
3. Pelagon, an "illustrious" companion of Sarpedon, who removes Tlepolemus' spear from Sarpedon's thigh.
4. Pelagon or Pelasgus, son of the river-god Asopus by Metope.
5. Pelagon, one of the suitors of Hippodamia before Pelops.
6. Pelagon, a native of Pylos who fought under Nestor in the Trojan War.
7. Pelagon, one of the Calydonian hunters.
