Hello!

Photo number five is one valve of a species called Pholadidae, but I don't know which one. I'm not familiar with shells from the Adriatic. It's definetely a shell. It might be Hiatella arctica.
I'm not sure about the rest:

I think photo 1 is Cerithium vulgatum with no lip.
Photo 2, I don't know, I'm sorry.
photo 3 looks like Hinia incrassata.
Photo 4 belongs to Naticidae family, but again I don't know which one.

I hope this is of some help to you.

Best wishes,
Emma.

Thanks, it was helpful.
At least family is helpful, then I allways check google for local resources to see what exists here.

first I' agree with emma, second is nassarius corniculum, 3rd again agree with emma but the correct name actually is nassarius incrassatus, the naticidae is a euspira pulchella. the last: yes is a shell. is a one valve of pholas dactylus
