During the Green Lantern movie panel that this year's Comic Con, it was revealed that 30 Green Lantern Corps members would appear in the film. Here's a rundown of the ones who have already been confirmed:
HAL JORDAN - Main character Hal Jordan was a captain in the United States Air Force, like his father Martin, and a test pilot when he was suddenly drawn to a crashed alien starship. The inhabitant, Abin Sur, explained (using his power ring to translate) that he was a member of the Green Lantern Corps. Mortally wounded, he searched Earth for the most worthy successor to pass the ring on. Hal, chosen because of his fearlessness and honesty, was given the power ring and its battery, becoming the Green Lantern for Space Sector 2814.
SINESTRO - Hal Jordan's "mentor" A native of the planet Korugar in space sector 1417 (as the Guardians designate space), Thaal Sinestro was originally the greatest Green Lantern that the Corps ever had. He had the skill, discipline, and courage to take on any crisis that may occur. He was also known for having the most orderly sector in the cosmos.
TOMAR-RE - Hal Jordan's "spiritual guide" Tomar-Re was a scientist on the planet Xudar before joining the Green Lantern Corps. He became a pivotal member of the Corps, training new members. He investigated reports of abuses of power by Sinestro on Korugar. He was close friends with Abin Sur, Green Lantern of neighboring Sector 2814.
KILOWOG - Hal Jordan's "trainer" Kilowog was a geneticicist and one of Bolovax's most brilliant minds. After the previous Lantern, Branwill, died, Kilowog was chosen to be a member of the Green Lantern Corps. Kilowog carried out his duties with pride. He would go on to be one of the Corps' best recruiters and trainers.
ABIN SUR - Hal Jordan's predecessor Originally a history professor on the planet Ungara, Abin Sur was soon appointed Green Lantern of Space Sector 2814 in the mid 1860's. He was the predecessor of Hal Jordan, the first Green Lantern of Earth, and mentor to Thaal Sinestro.
SALAAK - Revealed by Geoff Johns at 2010 Toy Fair Selected by Guardians of Oa to be Green Lantern of Space Sector 1418. A famous pessimist and loner, Salakk was a creature of protocol and laws. His skills as a master multi-taker makes him pivotal to the fluid operations of the Corps.

When it was desired, its affliation with Green Lantern Corps is marked by its folliage that was arranged into a green band circling the body with the standard Corps lantern symbol.

Boodikka was part of a group of warrior women called the Bellatrix Bombers before becoming a Green Lantern.
BZZD - Revealed at 2010 Comic Con Although Bzzd was no bigger then a housefly, his tremendous willpower
allowed him to be a capable fighter in the Green Lantern Corps. Bzzd's power was evident in his penchant for creating constructs that were massive in scope when compared to his diminutive size, like locomotives and full scale roller coasters.
GREEN MAN - Revealed at 2010 Comic Con Green Man was the adopted name of the Green Lantern from the Space Sector designated 2828 by the Green Lantern Corps. Uxorians frowned upon individuality, and in Green Man’s own words, “On Uxor, all are one.”

Stel serves the Green Lantern Corps though many of its battles, including a breakout from the Prison Planet of the Guardians of the Universe, an invasion by Qwardians, and an attack by the alliance of Nekron, Lord of the Unliving and the rogue Guardian Krona.
