* Helios: This was the most common name, personified as a god who drove his chariot across the sky each day.
* Hyperion: A Titan, Helios' father. Sometimes used interchangeably with Helios, but technically refers to a different entity.
* Phoebus: Meaning "bright" or "radiant," this was an epithet for Apollo, the god of light, music, and poetry, who was often associated with the sun.
* Sol: A Latin name, but also used by the Greeks as a synonym for "sun."
So, it really depends on the specific context and usage. "Helios" is the most common and recognizable name for the sun in Greek mythology.
