There isn't a sure way of knowing, but Tetsuya Nomura did mention that Kingdom Hearts III will bring Sora back, and we're forced to assume that means Riku and Kairi will be there, too.

You can't fight Riku in Kingdom Hearts II.
No. Riku never dies in Kingdom Hearts II.
Kingdom Hearts 3 has not been announced and currently is not in production. The story is unknown.

Riku does lots of things in the kingdom hearts games. Riku tries to gain power and fights his friend sora. and he does more stuff
Kingdom Hearts
Wear clothes like Riku.
No you can't. But if you have the Kingdom Hearts 358/2 Days for DS you can play as Riku in mission mode.
no
You cannot play as him in kingdom hearts 1 but you can in kingdom hearts: chain of memories.
Riku is in Kingdom Hearts because he is one of Sora's friends on Destiny Island, and an important character in the series.*Slight Spoiler*As we later find out, Riku's destiny was written when he was chosen as a Keyblade-wielder, during the events of Kingdom Hearts Birth by Sleep.
