Ooo, your first image of Yara is actually Raja. Yara's recording-a-hit-single outfit is the one with the gold shoulder pieces that you have later on, and they both have microphones because they're performing their singles. It's a bit confusing since they're both thin and have tattoos on their arms, but I'm pretty sure that is Raja.

That means we have four outfits that Raja is wearing so far which pretty much means he's a shoe in for top four/top three! (American Indian, dark brown and straight hair, Carrie (again?), and balloon-studded pink and blonde hair)
