If #2 is Elle Ray Cannons (not entirely convinced) then it looks to me like it might be the same person in pic #3 as well in which case it's just a question of who is in the yellow bikini beside her?
EDIT: Didn't notice the tattoo on her arm. But you can't see her other arm in the other pic, and the image might be flipped... or she didn't have the tattoo then... and so on and so forth.
