I haven't answered, because I don't know a good answer for sure. The first one looks like a Yadkin type point, but is a bit different from the usual one. I would call it some type of Woodland-era arrow point. The second one is an unfinished late-stage preform that hasn't had its final thinning, notching/stemming, and sharpening. Without the notches or stem, it's hard to ID what type it would have been, unless it was found in context with finished points.
