Here's some facts for you (spoilers)
Sora was not originally the keyblade master, it was supposed to be Riku, but Riku gave into darkness, thus throwing away the keyblade. This is why he could take it from Sora in Hallow Bastion.
The reason Riku can use the keyblade again (kh 2) is because he excepted what he was, and he came out of the darkness that consumed him. Therefore, he could wield it again. What triggered this, his fight with Roxas at Memories Skyscraper. He fought with a keyblade in this battle.
Now why can Roxas wield 2 Keyblades? Xion, was basically Roxas' other half (sorta like his nobody) she was a clone of him. But she still was a being capable of learning. She learned how to use the keyblade. But at the end of 358/2 days, she became one with roxas, and that gave him the ability to use 2 keyblades.
These are just theories, but in the first one, about Riku being the original keyblade wielder, is 100% true, dont know about the rest of that theory or the other ones though
