In photo #3. Flint or chert, Basalt is the all black smooth piece and the larger ones look like a possible tooth. I think you need to go back to photo # 1 and look at the face in the bottom right corner. Nice finds and good eye man, you have stone tools. Most likely old as hell... Go through every piece you have and look for wear marks where they would have been tied to a stick and look for knapping and smooth spots where your hand will fit the item nicely like it was worn that way. Try both hands and they could be left handed or right handed....
