Frisk is a human, the only magicial ability she has  is the ability of saving/reseting everything, more likely because to make you think you are the controller of this game.

As for Chara, she's dead, it's pretty much normal if she acted unhuman-like during the Genocide Ending such as Erasing the world/Taking you

They also possess a human soul which further defines a human in the Undertale universe. Yes, I think they just follow your choices or decisions. You just guide them, not control them, as Chara says.

I'm not sure about it, but could it be that Chara could temporaly appear and talk to you because they are kind of like Asriel? I don't want to insist in the reincarnation theory if others don't believe it, but I think that just like Asriel's dust is inside Flowey, Chara's soul is inside Frisk since Frisk would be their reincarnation. So maybe thay can get that temporary apparition because of it?
