sorry for the pictures but i`m learnig how to use the picture posted

The first one appears to be an Olivella, not an Ancilla. May be Olivella volutella (Lamarck, 1811), but I am not certain of the species. The specimen is rather worn and faded.

The second shell is an immature Atlantic Gray Cowrie, Cypraea cinerea  Gmelin.

The third one is Nitidella nitida (Lamarck), in the family Columbellidae.
