Nice finds, and I assume you found them in Texas? The grey flint item in the center looks like a bifurcated point, maybe Lecroy type. The whole top row, and the furthest to the right on the middle row, look like reduction flakes of nice material. The furthest item on the left in the middle row looks like a nice stemmed point, as does the one on the bottom right, with just the tip missing. The item on the bottom left looks like it might be a natural rock in the general shape of a stemmed point with tip missing? Looks like a nice area to find artifacts, Good luck in future hunts.
