Jason's accompaniment is called the Argonauts (literally "Argo's Sailors). There are 84 named Argonauts, too many to put here, but some of the more notable members of the expedition were:
Iolaus and Heracles
The Boreads (sons of Boreas, the North Wind, who were said to fly)
Augeas (the father of Theseus)
Bellerophon (the slayer of the Chimera)
Castor and Pollux (the twins immortalized in the constellation of Gemini)
Deucalion of Crete (the son of Minos that was killed, creating the tension with Athens)
Laërtes (the father of Odysseus)
Perseus and Theseus are also commonly cited as being Argonauts, but they likely weren't, because Perseus was Bellerophon's Grandfather and would have been too old, and Theseus was Augeas' son and would have been too young at this point.
