Hoch chab = each pie
Hoch chabmey = all pies
HochHom chabmey = almost all the pies

HochHom thing(s) = almost all of the things is not found in canon, but I think no one would find it exceptional.

chab Hoch = all the pie
chab HochHom = almost all (of the) pie

thing HochHom = almost all of the thing is found in canon; thing Hoch = all of the thing is not. The latter is an extrapolation based on the former.

Would the following make sense ? Would they actually mean anything,
and if yes then what ?

chabmey Hoch
HochHom chab
chabmey HochHom

You're asking about explicit plural suffixes or their lack. The answer is we don't know.

If I had to guess, I'd guess that chabmey Hoch pies' allness refers to the totality of the group of pies (rather than to the pies themselves), HochHom chab means exactly the same thing as HochHom chabmey, and chabmey HochHom pies' almost-allness refers to the not-quite-totality of the group of pies.
