Fossil Shark Teeth ID Project - Part 2

I am currently working on a shark teeth ID project. It is a personal project I am working on because I got gifted a multitude of fossil shark teeth of various species.

Up untill now I have only been able to identify one shark species, because the teeth are so characteristic. The teeth (seen in the picture below) belong to the species the Broadnose Sevengill Shark or Notorynchus cepedianus.

The Broadnose Sevengill Shark belongs to the family of Cow Sharks or Hexanchidae, which are considered the most primitive of sharks.

I actually just recently watched a documentary covering Broadnose Sevengill Sharks with Forrest Galante. It was called 'Alien Sharks: Strange New Worlds', it was from Sharkweek 2023 and it was really good!

I also have two different teeth which I am having a lot more difficulties with identifying (see the two pictures below). If anyone has any clue of which species these teeth may belong to, please let me know:)
