Yep, I'd call that one a Palmer, for certain if the base is ground. And the broken base looks like a possible Hardaway side-notch, pretty rare and old point. The others are just broken fragments, hard to say what they were. I doubt if any stone points were used to spear fish, that was likely and atlatl dart point for spearing big game and people. Fish points were usually just carved wood , cane or antler-no need for a stone point, and the binding would get wet and loosen anyway.
