We'll we know they can shapeshift. As far what makes someone a  Druid  the word means "Wise Oak" and indicates a dedication to philosophy and religion. We don't know if you have to be born into it or not. While don't truly know if they are supernatural or not remember but I think they might be. In season one episode Formality when Peter threw the chair at Deaton he didn't even flinch leads me think something.
