ZF and ZF.2 are Nikon F mount, the latter with a chip so that you can get full EXIF, set the aperture with the wheel and use matrix metering.
ZE is Canon EOS mount.
ZS is m-42 mount I believe, although these are discontinued now.
ZA is Sony A mount, and are completely different lenses from the above, which are all optically identical.
The Hasselblad lenses are called Hasselblad, IIRC, and not Zeiss, although they are made by Zeiss.
ZM lenses are Leica M mount, and are completely different designs, generally not as good as the SLR lenses, with possibly 2 exceptions: 18mm f/4 and 25mm f/2.8. The 85mm f/2 might also be very good, but it is so big and expensive that everyone just buys a Leica instead
CY or C/Y is Contax/Yashica, a 35mm film mount corresponding to Contax and Yashica cameras. These are very good lenses, and the more modern ZF/ZE/etc lenses are often closely based on these designs. The 21mm f/2.8 Distagon is probably the most famous example.
CV is probably Cosina-Voigtländer, and has nothing to do with Zeiss, other than they are also currently made by Cosina. The Hasselblad lenses are C, CF, CFi, CFE and FE series. I own three FE lenses. Very good lenses, and some are good enough to still be good adapted to a DSLR, but not all.
There are also Contax 645 lenses, as well as the Zeiss lenses for the Rolleiflex 6008/Hy6 system, and these two systems have some of the best Zeiss lenses ever made. Then there are Contax G lenses, which are small AF lenses for a Contax rangefinder-like compact film camera, I believe, although you definitely want to check a better source for that. These are currently only interesting for Contax G or NEX, m4/3, etc. users, and are problematic to adapt, although very good.
There are also some Zeiss large format lenses. I know little about them, but they are apparently well regarded in the rendering department, but have very small image circles compared to Schneider or Rodenstock lenses, and are somewhat rare.
I think I covered everything, which probably means I didn't. Oh, Nokia has a high-end range of cellphones with Zeiss lenses
