I see Frisk as either a boy or a girl, because there's not really any implications towards any gender for them whatsoever. However, I'd say if anything, Frisk leans towards being a boy.

For Chara, I'd say agender, MAYBE leaning towards female. This is due to how Asriel refers to Chara as them, but how they basically appear like a female child.

Monster Kid? Definitely male. Referred to as male and all that, and seems to act just like a fanboy.

River Person? I'd say genderless, I suppose. Not really any evidence pointing to anything, but I do interpret them as female for the same reason as Comic.
