shell identification help

[newshell]

Hi Paul,
Thanks a lot for your help on this, may I know what is "iffy" ? After making some comparison on the picture, I think the shell 6 is angaria delphinula.
Please find the link below on the ventral view of some of the shells

I hope the picture can come out, as I was having some problem to upload the picture just now.

Do you mind sharing some of your thoughts on 'starting the hobby of shell collector' ? I tried to start this hobby but so far still have concern/questions on the following:
- So many different type / family of shells, usually people start with random collection or just focus in 1 or 2 family
- Any possibility to have the information on the special visual characteristic of the shell families? By just looking at the picture, you can easily know they are from which family,and maybe their name, I believe all families have those characteristic, something like conidae=>the shape like cone, etc.
- I have difficulties for the space to keep those shells, any idea of other than putting them into small container/drawer, what are the other option to keep them, I prefer to have them always available at sight, but having them display all over the house or making a special glass rack for them sounds like a bit too much.
- "does size matter?" Usually when I bought shells, I will like to look for the largest available, but recently I take the smallest available but with the most original/strong pattern because of the space issue, what do you think?

Thanks a lot my friend.

Rgds,
