Just had a look at Reno's files for the Gongaga scene, here's what he uses:
Skeleton/.hrc file: DHAF (this one has no eye/mouth textures and seems to have been designed to use Cloud's animations; probably because Reno didn't have enough animations of his own for this particular scene).
Animation Files (in order)
ACFE: Standing/Idle
AAFF: Walking
AAGA: Running
AAFE: Standing/Idle
BZCE: Shrug
AVJE: Taken Aback
AJEB: Head scratch
AQBF: Turn Right
APEE: Raises Fist
Seeing as a lot of these animations are shared by Cloud and a lot of NPCs it's probably either the DHAF skeleton that's busted or the flevel is looking for the wrong animation files. Now, I tried giving Reno his usual standing/idle animation (AOJD) and it resulted in him getting tangled into a ball so his usual skeleton (AODD) and animations are incompatible with DHAF and most 'default' animations that Cloud and other NPCs use. So either DHAF.hrc has gotten mixed up with AODD.hrc somehow or it's the animation names that are wrong (it should be looking for the animation files listed above).
Now about Makou, have you tried moving the flevel to the Desktop and opening it up from there? Makou is a bit strange in that it can read an flevel that isn't in the FF7 data folder but it'll go to the FF7 data folder to get all the other information that it uses (for instance, it'll read the char.lgp that's in the FF7 data folder regardless). If you can get it to work, then check the Gongaga scene (gonjun2 - 515) and hit Ctrl+M; this'll show the models and animations used in that scene. If DHAF is missing or if the animation files used aren't the same as above then that's the source of the problem (rename them by doubleclicking, then just type in the correct name). If they are the same, but showing as a jumbled mess anyways, then there's something wrong in the char.lgp with these files.
If Makou still isn't working for you though then I could maybe make a quick patch for your flevel, see if that fixes it. Problem there is you'll lose any changes you've made to the flevel already (like dialogue, maps, scripts, etc.)
On an unrelated note, that is a damn fine profile picture, cmh175.
