Does the hole go clear through the piece in the first three pictures? That could be a Chumash Pipe. The round stone could be a Mano. Not sure about the piece with the engravings. It almost looks like a old printing tube that would be rolled in ink and then rolled on paper to print out the pattern. The other rock with the hole is most likely natural.
The one with the hole on each side goes in a 1/2 inch on each side and is 3 1/2 long
The one with a hole at the top has a number on it 66168-6 and 54 in ink on the side. In looking closer at the hole it looks like it has been worked. It does have a patina to the rock. It is hard to get a good picture of that one.
The round one has a slight indentation and ridge on one side not deep enough to be a nutting stone. The other side is smooth.
It could be a unfinished pipe, like the style Grimm was talking about. The small stone with the cup on one side could be a game stone and the item with the engravings I would bet it's not NA. Cool buys
