Main Characters
I am assuming you mean the film version (since you refer to it as simply The Last Airbender), then the characters are…
Aang: The Avatar. Also the Last Air Bender.
Katara: A Water Bender from the Southern Water Tribe. Is Aang's Water Bending teacher. Also Aang's love interest.
Sokka: Katara's older brother. Also a warrior from the Southern Water Tribe.
Prince Zuko: Exiled Prince of the Fire Nation. On a search to capture Aang to redeem his honor. Technically he is a villain, but he in a way he's more of an Anti-Hero.
Uncle Iroh: Zuko's Uncle. Same as Zuko, he is an Anti-Hero.
Admiral Zhao: Admiral of the Fire Nation Navy. On a search to hunt and kill Aang. He is a villain through and through.
Appa and Momo: Aang's pets. Appa is a Giant Flyign Bison. Momo is a Bat-Lemur.
However, this is merely for the first film. Characters from the next two seasons of the show include…
Toph: A blind Earth Bender. Uses Earth Bending to see (like Dare Devil uses sound waves). Is Aang's Earth Bending teacher.
Princess Azula: Zuko's sister. Sent to capture Aang. She is the most evil villain in the show.
Fire Lord Ozai: Zuko and Azula's father. Chief Villain of the series. ((he may appear in the film, but in the Series he was not shown in person until Season Three, so I am assuming he will not be.))
There are many characters in the tv show from the ones you see once or twice to the main characters. The main characters are Toph,Sokka,Katara,Momo,Appa,Prince Zuko,Princess Azula,Firelord Ozia and the most important character of all Aang, the last airbender and also the avatar.

Toph Bei Fong: The daughter of the wealthy Gaoling Bei Fongs. She was born blind but used her blindness to become one of the greatest earthbenders in the world. She is tough, abrasive, and a tomboy but can compassionate when she needs to. She is Aang's earthbending teacher and friend.
