Care to place the terms in context? What document (or other media) are you seeing these abbreviations on? Are they related to a particular system - e.g. flight planning/dispatch, weight & balance system? A specific manual?
Might help in deciphering what they may mean.
As far a I am aware the only 'industry standard' abbreviations in respect of zero fuel weight measurement are, EZFW, RZFW, ZFW (or even AZFW) and in use with balance condition, i.e. MACZFW LIZFW.
What you are illustrating above seem somewhat proprietary to perhaps a particular system and/or carrier.
