What are the differences in ROMs that are from different countries? Like for the S4 GT-i9500 4.3, There are some many country versions. Is it just localization differences? or something at system level?

If you install different countries ROM, you will get some different app that follows in that country region.
Yes, it's OK to flash stock ROM from another country. BUT, take note that it may have different languages, and a different baseband/modem. Having a different baseband can cause network issues (or a very hot phone), but you can flash a baseband that works for your country.
