It depends.

Maximun file size is determined by the default block size.

If using: ls -sal : your directory size is 4096 then your maximum file
size is 2G.

I dont know about a maximum number of files for a directory, but i do
remember an article a while back talking about the accidental creation of
65536 files in a directory bringing the system to a crawl. (Article was
discussing the advantages of journaling file systems)
