Interesting stones or maybe fossils?

[Granny and Aust]

I’m really new to fossil identification but my nearly eight year old grandson’s recent passion has sparked my interest and we have been going through some of my beach stone pick ups I’ve always picked up interesting looking (or interesting feeling)stones and what I thought were shells- turns out I have quite a few fossils.

The flint photos below were found on Whitstable Beach in Kent England. I joked and called them witches fingers but now I’m wondering… are there crinoids on the surface or just marks.

The second  stone I can remember one of the grandkids giving to me as it looked like a bird it is probably from Whitley Bay or Roker beaches in Tyne & Wear England I wondered again about a fossil either sponge or coral. 
From what I’ve read I’m assuming the 3rd stone is a sponge? Again just picked up and pocketed as it felt nice and looked different. 
These are just a few of my finds, it’s amazing what you can find when you are not looking. 

thank you for any help you can provide.

Hi, i think the last item might bé a worn coral.

These don't really look like crinoid bits to me, They could be foraminifera, or possibly calcareous algae ?
