Littoraria lutea? Or a similar littorirnid species?

I definitely have 1 littoraria angulifera. But the rest i cant make up. The shells are different from the lutea. I went to the lfs and asked them to pack them for me as i am on a one day trip 350km from my house and he didnt know what they were too lol. I hope these eat algae tho sunce they were on rocks covered in algae
