The first piece is chert, by the looks of it 

The other two I can't tell for sure, need better close-up pictures, but I also think probably rocks.

But….you came here asking a question? If the intention is to assert what you already “know” your finds to be, there’s a general fossil discussion board on this same site that’s a better fit. You’ll probably still have folks telling you that you’ve got rocks, but it would at least be slightly less confusing for all involved. 
For what it’s worth, if you ARE asking what you’ve got, my amateur opinion is also rocks with the caveat of the last piece being too wet/distant in the picture to be sure. Could be petrified wood.

Another good thing to include if you’re trying to get professionals to weigh in is location. In a clay pit isn’t enough, even just a country, state or province isn’t enough. The more specificity the better. There’s lots of good reading on this very board, just above this very post, that lays out a lot of good advice. You should use some of your time, while you’re here, to learn some!

I've already obviously wasted my time answering your question if that's all you have to say.

What an impertinence !

the fibrous nature of them could be suggestive of small slivers of petrified wood, but it's difficult to tell.  The fibrisity (is that a word?) could also be due to mineral foliation; i.e., metamorphic rock
