Agnosticism pertains to lack of knowledge. It is not a religious belief or position unlike all the other options listed. An agnostic can either be a theist or an atheist.
partly jewish, part protestant. but only the jewish parts of my family are at all practicing. I identify as Jewish because I am more connected to that community (I live around many jews) and my mother is jewish and it goes by the mother's religion. but i am not super orthadox about that.
