Can anyone tell me what keyblades there are for Terra and where to find them?

By Terra's Keyblades, I presume you mean his exclusive ones? If not, you get them after you complete a world or defeat an enemy.

Earthsaker: Terra's starter Keyblade. First Keyblade you use when playing as Terra.

Ends of The Earth: You get it after Terra goes to Destiny Isle.

Darkgnaw: Recieve it after you beat the Dead Ringer event in the Mirage Arena.

Chaos Ripper: Receive it after you defeat Master Eraqus.

Gamefaqs has all this information in its guides usually. Check there to be sure.

Dude I'm pretty sure you would get a better answer at kingdomhearts.wikia.com/wiki/Terra
