There are quite a lot of demigods in the Percy Jackson and the Olympians series. They are:
*Note that there were several other half-bloods whose names were never mentioned such as several Cyclopes and the half-bloods that come to Camp Half-Blood at the end of The Last Olympian.
Percy Jackson's brother in the "Sea of monsters" book is, Tyson.
Their names were Kelli and Tammi. They were cheerleaders at Goode High School.
Tammi and Kelli were the names of the monsters that were posing as cheer leaders in the Battle of the Labyrinth.

Their names are, Percy Jackson the Son of Poseidon, Grover Underwood the satyr, Annabeth Chase the Daughter of Athena, Chiron the camp trainer and centaur, Dionysus the god of wine and camp director, and Luke Castellan the turned away Son of Hermes. There are more like, Sally Jackson; Percy Jackson's mother. They would be too much to list, though, so I gave you the main characters.
Percy Jackson
they are:the lighting thief, the sea of monsters, titans curse and the battle of the labyrinth. Also just in case the fifth one is the last Olympian

In Percy Jackson there are 12 olympian: Zeus, Hera, Poseidon, Demeter, Ares, Hermes, Hephaestus, Aphrodite, Athena, Apollo, Artemis, and Dionysus.But in the books there is a mistake. Dionysus is not an olympian. It is Hestia.
Jason and the Argonauts. Or if you mean in the Percy Jackson and the Olympians series Percy, Annabeth, Tyson, and Clarrise But if you want to specifically know the names of each of the Argonaut heroes, read Part 1 chapt. 4 of Padriac Colum's book. It lists them there.
