Doughnut hole, artifact, or rock?

[BearCreek]

I am brand new to artifact hunting, but have been blessed to move to a farm in northwest Georgia with a very old creek that is turning up numerous "interesting" rocks. The area I am finding things in is near a sharp bend in the creek with a good sized sand and rock mound. The creek banks are about 7 feet. These are some things I found this week. Any help with ID will be very appreciated.
