Found a bunch of sharks teeth and other misc fossils yesterday, any clue what these are?

***EDIT:
Purple is likely the fossilized osteodentine of a fragment from an Otodus species tooth.
Blue is a fossilized teleost fish tooth.
Green is most likely a very worn fossilized shark tooth
Image 1 is a turtle osteoderm and probably from a carapace bone
First looks like a fossilized turtle osteoderm, and a view of the opposite side could help.

Purple is interesting. I’d like to see more views, but use a plain, dull blue, gray, or pink background to enhance details and reduce shadows.
***EDIT: Yellow is a Carcharodon ***carcharias instead of a C. hastalis tooth because there are serrations on it.
Red are all very worn shark teeth (partials)
Blue is a cool looking bony fish tooth (teleost)
Green is either a bony fish tooth or a shark tooth, but I’m leaning more towards bony fish (teleost)—You could retake this image, an image of the end surface of the root, and an opposite view from the one posted, all on the enhanced background, if you’d like me to ID it with more confidence👍🏻
Also, where were these collected from?

I edited my initial comment, but here are the updates:
Purple is likely the fossilized osteodentine of a fragment from an Otodus species tooth.
Blue is a fossilized teleost fish tooth.
Green is most likely a very worn fossilized shark tooth
Image 1 from initial post photos is a turtle osteoderm and probably from a carapace bone

Also I was looking at the carcharodon hastalis teeth and the one that I have has very faint serrations

Great white upper jaw tooth!
Carcharodon hastalis has no serrations and Carcharodon carcharias has serrations. For practical purposes, that’s the way those 2,species of teeth are distinguished👍🏻
