Yes, by increasing your AP when you level.
Riku's last name was never mentioned in the Kingdom Hearts series.
Yes Diva loves Riku very much but his death on episode 32 was an accident. I mean Diva didn now Riku was Saya's chevalier. So Diva though Riku was still human and she wanted to make him Diva's chevalier.
Maleficent gave it to him
although diva seems to have a crush on riku (as strange a crush as it may be) it is belived that she wore his face to mock saya, reminding her who killed her brother.
Quoted from Gamewinners.comOblivion Keyblade:After defeating Riku for the last time in Hollow Bastion, return once you regain control of the Gummi ship. Go to where you fought Riku and go up the stairs to the wall opposite the Keyhole entrance. There will be a chest there containing Oblivion, one of Sora's strongest weapons.
Yes, Riku is playable in Kingdom Hearts: Chain of Memories.
To play as Riku in Chain of Memories you have to defeat Marluxia as Sora
If you are talking about the original Chain of Memories for the GBA, then it has 78 sleights for Sora, and 5 sleights for Riku. In the remake of Chain of Memories for the PS2, Sora has 83 sleights, and Riku has 13 sleights.

Yes. In Kingdom Hearts: Chain of Memories, Vexen made Replica Riku was as a plan B when his initial plan of recruiting the real Riku didn't work. While in Castle Oblivion, Vexen created a spitting image of Riku infused with Riku's memories, but the memory was altered and manipulated by Namine in order to further fault Sora's plans. This plan failed when Namine told Replica Riku the truth of his existence.
