Please help me identify some cowries I found in Mozambique?

Please help me identify some cowries I found in Mozambique?
Hello, I hope that you can help me identify these shells. My local library only has one book on seashell identification, and it does not cover these shells. Any help would be truly appreciated! I found these all dead and some are in very poor condition or just under-fossil, but I have enough of the same types that I hope we can still identify them. My apologies that the photos are a bit dark. I believe I have 5 different species, and I have indicated them by numbering since I don't know their names.

1. Large white shell with red-orange inside
2. Medium green shell
3. Small white shell with green top

1, 2 and 3, top view: (please note that the two smaller shells are green colour, the picture just doesn't show it very well)

1, 2 and 3, bottom view:

1, inside:

4.  White shells with light orange/cream banding on top, small lighter brown spots on top, and fewer, larger dark brown spots on sides. I believe the shells in this photo are all the same species. The three shells on the left are partially under-fossils (the upper layer with the spots has worn away on top).

4, top view:

4, side view:

5. White shells with purple top with light orange spots and yellow-orange stripe on each side (the ones where the orange stripe is missing are under-fossils).

5, collection:

#1 is Ovula ovum, not a true cowrie but a member of the family Ovulidae.
#2 not sure - straight-on dorsal and ventral pictures may help.
#3 is Cypraea annulus.
#4 includes 4 different species.  The first shell is Cypraea vitellus.  The second and fourth shells are Cypraea lynx.  The third shell could not be identified dorsally because it is either immature, or the mature pattern has been eroded away.  But the ventral view looks like Cypraea caurica.  The last little shell doesn't show enough detail for a positive ID.  It may be Cypraea hirundo or Cypraea kieneri, but can't be sure from this image.
#5 The shell shown in both pictures appears to be Cypraea helvola.  The shell that appears with it in the first picture appears to be Cypraea erosa.
