Unknown beachworn conus

[wateryworld]

These five cones were given to me, so I've no idea where they'd be from, but I'm assuming they are rather beachworn due to their unusual coloration.  The only one I was able to find in the book was called conus sponsalis.  Does anyone have any idea what these could be?  Purple and pink don't appear to be standard cone colours!  Is this due to bleaching?

Thanks!

The first picture is certainly C. sponsalis. 
The second one (unknown cone 1) is very eroded, but the pattern would suggest C. ebraeus.
Sizes would be helpful on these.

My apologies!  Sizes have been added to the images!

Okay, I've tried to narrow the ID down a bit, I've put down their potential names as ebraeus, rattus, varius and namocanus.  Can anyone confirm?

Thanks!

So, nobody knows, then?

Some are VERY worn, I would agree with your identification except #4 which looks to me like a juvenile C. magus. Not too sure of #3 either.
