I've never heard of any limit..
For Texture Only d'loads that unzip to a 'texture.xxx' folder containing the new textures and a Text file containing instructions for creating a new [fltsim.x] section or preferably a [fltsim.x] section to paste into the aircraft.cfg, here are a couple things to check.
Make sure the texture folders are in the proper place, and that the suffixes, texture.
new
, are unique. (Which of course they would be or you would have been prompted to 'overwrite' when installing.)
Things to check in the [fltsim.xxx] sections, in aircraft.cfg.
[fltsim.

ui_manufacturer=Airbus<----the same for grouping in 'select aircraft' window
ui_type=A300B4-200 <-----ditto or not, depending on how you want to group.
ui_variation=Continental<----unique for ease of finding in group.

Hope this is helpful.
