They're all synonymous, so I'd say that they're different names for a
double-sided, high density 5.25" floppy. The difference between 135
and 96 is probably sector sizes. In any case, I wouldn't worry over
them at all.

When's the last time you saw new modes for 5.25" floppies? I'm not
being sarcastic; I'm just pointing out that they're all obsolete.
