What is the limit for the total number of tiles that can be in a tileset?
Technically 4,294,967,295 entries. However due to technical limitations you will be lucky to make 1 billion entries before the file becomes too large or you hit an Out of Memory error due to WC3 being 32bit. Same limit applies for cliffs but they are counted separately.

That said only the first 16 tiles and 2 cliffs can actually be used. This is because the game only allocates 4 bits for tiles and another 4 bits for cliffs. The cliff limit is some other hard-coded constant as in theory 16 cliffs are supported.
 
The most you can get in the regular editor is 13 (?) through Advanced -> Modify Tileset.

JassNewGenPack (in our 'tools' section) allows you to get up to 16. Follow these instructions to put them in your map:

Note that you only need JassNewGenPack to add the tiles to your map. You can edit it in the regular editor after you've done so (if you'd like).
