Hello,

Some of these are difficult but I'll do my best.

#1 appears to be a member of the family Veneridae.  The shape suggests Meretrix meretrix.  The color pattern is unusual but the species is quite variable.

#2 is also in Veneridae, a species of Tapes, probably Tapes platyptycha

#3 seems to a mix of things.  The first item could be a piece of the base of a cowrie shell, a fairly large species, perhaps Cypraea tigris.  The second one, no idea.  The third and fourth could be the upper valves of a small oyster called Lopha frons, not sure though.

#4 appears to be Ergalatax contractus, in the family Muricidae.

#5 is pretty badly worn, but is also Muricidae, perhaps Morula granulata or a small Thais.
