Your first image is of a piece of Cretaceous flint probably from the Flamborough chalk, looks like it has what's left of a sponge inside but it's hard to tell.
Second and third images are of a piece of Lower Jurassic matrix.
Unable see any fossils present so hit it on the beach, if you found something inside of it you can identify wether it is from the Upper, Middle or Lower Lias.
Your fourth and fifth images are of a fantastic septarian nodule, it's were water has seeped through cracks in the block and deposited minerals, these look fantastic cut and polished and sometimes when split with a hammer they have some nice crystals inside.
Hope it's ok to attach a couple of images of a septarian nodule that I split today furter south to were you have been collecting.
