Scott:

Your photos marked fff.bmp and tyu.bmp. are probably both
Melanoides turricula (I.Lea, 1850).
The one marked mmm.bmp is Elimia floridensis (Reeve, 1860).
The sinistral one is a Physella. They are rather difficult to I.D. beyond the
genus level,
but locality data helps narrow the possibilities.
Also, I've heard that Utterbachia is a synonym of Anodonta.
