All look natural to me, but the one with the square edges could have been a used piece from knapping. One does have the shape of a point but it is natural.

The one that is shaped like an arrowhead is what i call a fooler some folks calls it a faker

The top two pics are native pottery. The arrowhead shaped piece is a natural. The other pieces are the kind of rock that you should be looking for. They look like flakes from making points.
