You could have some there hard to tell without a very close inspection, look for etched areas around the edges where the stone would have been napped off it will the same distinctive pattern from striking the stone. But from the looks of it I would say "yes" you found a few scrapers and cutting tools.
The one on the upper right is the best one. But you have posted this in the wrong place. There is a Artifact page in this site....you will have to look for it.
