These were all found on the same site within 20 ft of each other. 3 came from same spot around old oak tree about 4-6 inches in soil. I’ve found a couple points and loads of broken blades in this same hole.
Lots of flakes and broken and rejected bifaces in all stages of production, so a biface reduction site. See pages 155-214 of :

That being the case, the most likely explanation for the pieces in question is that there are the tested pieces brought to the work site for further reduction, but then either rejected or forgotten. With "tabs' or natural slabs like that, the first thing the knapper does is remove a squared edge to get a look inside, test the material and to set up a platform to drive thinning flakes deeper into the piece, just like on the pieces you show. The two pinkish ones: Is that color natural? Many cherts turn pink like that when heated, so maybe heat treating was part of the process at this work site.
Personally, I find the work sites interesting because they show you the process of how the stuff was made. Unfortunately they generally suck for finding points since the whole idea of the site was to make stuff to take away so whatever gets left behind tends to be junk. Still, you can get lucky. I have a really nice big blade (late stage preform) almost 6" long from a work site and saw one in a collection recently that was even bigger than that also found in a chip pile. Probably accidentally left behind. Also if the site is old enough, the paleo and sometimes the early archaic guys would often dump their old points at the work site after making new ones, so maybe...
You do realize chert rocks are some of the most common rocks in the Ozark Mountains and have been here for well over 300 million years right? Just because one of them could be made into or used for something does not in any way make it an artifact.

Same hole
Those are good pieces and not all from the same time periods.
Here's a sample of some pieces my brother and I have found in the last couple of years.

I was talking about the very first rock you posted in the thread, but before I finished and hit post, you had posted some good pieces that I made sure to compliment.What are you talking about?
Yeah and I’ve had people tell me that this spot is trash. I believe it to be occupied for quite some time. Like I’ve said in another post, I was taken to this site. I wasn’t the first one here looking. I’m just picking up what was left over
It's all good. Keep posting. It is how we all learn. I have a piece of knapped "limestone",lol. It's knapped in my mind anyways but yet have had one person agree with me.
