Avril,
Looking through your pictures, I'll venture the following
identifications:
#1 - Coralliophilidae; a very clean Magolopsis lamarcki?
#2 - Atys debilis with some pieces missing from its lip?
#3 - remains of a Cypraea after wave action as had its way.
#4 - juvenile Cypraea; the dark spire is typical of isabella
#5 - never saw one of these
Hope that helps...
Bob Dayle
