From their size I would say in the 1st photo the 2 to the left could be knife blades and the others dart points. Nice findssomeone from your area should know the type.
Looks like you have a great spot to hunt and bet you will find much more there. The one in the 3rd pic my guess would be Guilford but I'm not expert. Go to this link Virginia Projectile Points if you haven't already, they have pretty good examples and a local expert could probably give more info if there is one available. All are great finds and can't wait to see what you find next! HH
