10.  Viviparus malleatus (fresh water)  Originally from Asia, but now widespread in the United States

09.  Cancellaria oblonga, western Indo-Pacific region

08.  It's a land snail, may be an immature Achatina fulica which now exists practically worldwide in tropical and subtropical regions.  It grows to over 5 inches in length.

07.  Yes, Marginellidae - Marginella (Prunum) prunum, Caribbean

06.  There are a lot of these small Trochidae species, some of which are quite similar, but this looks like Tegula viridula from the Caribbean
