Scrapers or natural?

Any signs of being worked by man?

The two pieces I see at the top look like they're artificial, its difficult to tell with the 3rd piece. That sharp one probably was a scraper, or it could have been a simple cutting tool

By artificial do you mean worked?

Looks like flakes to me but I cant enlarge them to tell for sure.
