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
