I agree with what martin said. The two in the middle in wooden bases are novaculite of some sort, but I can't say for sure what. If they shed particles in use, perhaps a cretan. If not, they may even be one-off washitas, but the chance is that they're something else.
Of all of the stones, the hardest to identify are the green/brown, etc novaculite and the black/green/gray slates from the UK. There are so many.
