Avril,
The live animals are goose barnacles. These often attach to floating objects at sea.
The gastropods are a mixed bag. The smooth ones with crystals or agate inside (1,2,3,5 and 8) look like Physa, a common, fossil and recent genus of left handed fresh water shells. They are possibly too big to be in that genus. The two (shells 4 and 6) that look like Busycon are probably Florida Pliocene fossils. The presence of an other unrelated, Recent shell ( 7, which is not sinistral anyway) implies a 'collection' from multiple sources, not all local.
