Well, they very well could be. They appear to be a porous stone which has filled its cavities with silica rich waters which have developed into a porous rock which now has quartz crystals where voids used to exist. It is not outside the realm of possibility fossils adhered or cemented themselves to the rock. That would make sharkstooth, shellfish and coral the most likely fossils.

The first one definitely looks like a shell from a fresh water but the other hole doesn't necessarily represents what a shark tooth may appear to be like.https://www.essaychamp.co.uk/

Very worn petrified coral? If so, it should be limestone.
