Expect Pakistan, can you paste the countries list?
These are the most air force who can afford the 2nd tire best available aircrafts around thr world.
1st tire - 5th gen fighters
2nd tire - Rafale, EU fighter, su 35 and Saab gripen etc..
3rd tire - low cost flying machines - Jf 17 block 3, mig 35, might 29, Hal tejas mk1a etc.....
Definitely Hal tejas mk1a is very less chance for the export since itself not inducted in IAF.... Even I don't support for export as of now since 1st should be inducted in large number than only try to export......... Unsure, why is so harry furry by HAL
