Honeycomb:

Answer 1

So far only Honeycomb is a tablet-only version. Other versions are used on phones, tablets and other devices (TVs, android-x86 etc.).

Answer 2

While there are tablets that were able to munge other versions of Android to be used on a tablet form factor, only Honeycomb (Android 3.x) was designed specifically for tablets. (And, because of some of the kludgey wizardry they needed to do for that, they've not released the source code for Honeycomb.)

Ice Cream Sandwich is supposed to merge the phone-only (Gingerbread) and tablet-only (Honeycomb) codebases.
