I don't think you can.
You can only fight Terra in the Kingdom Hearts 2 Final Mix+, he is called "Enigma Soldier". Sorry.
You don't meet Terra in Kingdom Hearts 2, you meet him in Kingdom Hearts 2:FM, I think he shows up in the Cornerstone of Light in Disney Castle.
He isn't
You can only met him in KH2 Final Mix. How, I do not know
Kingdom hearts II final mix is an extended Japanese version of Kingdom hearts II with more bosses including Terra from birth by sleep and a bonus secret ending.

Roxas, or also known as Sora's Nobody. Kingdom Hearts 3 is titled as "358 / 2 Days" for the Nintendo DS.

Birth By Sleep will. Kh3 will most likely be with sora and friends because it will tie together Kingdom Hearts Birth by Sleep, Coded, and 358/2.
www.kingdomhearts.comIt's a portal site for Kingdom Hearts, Kingdom Hearts 2, Kingdom Hearts Chain of Memories, Kingdom Hearts 358/2 Days and Kingdom Hearts Birth by Sleep.
Probably not. But, there is going to be another one for PSP which is Kingdom Hearts: Birth By Sleep which takes place 10 years before Kingdom Hearts. *SPOILER* The main charatcers have to deal with something related to Sora Kairi and Riku, which are Ven, Terra, and Aqua.
If you mean the order of which they were made, here it is: Kingdom Hearts, Kingdom Hearts 2, Kingdom Hearts Chain of Memories, Kingdom Hearts 358/2 Days BUT THIS IS THE ORDER THEY ACTUALLY GO IN: Kingdom Hearts, Chain of Memories, 358/2 Days, Kingdom Hearts 2. Also, the other 2 upcoming ones: After Kingdom Hearts 2 will be Birth By Sleep (on psp) and Kingdom Hearts 3 (most likely on ps3)
