Fifth generation (although all these generations are debatable) requires not only best engines and aerodynamics, but also a trade off between aerodynamics-stealth and engines-stealth. In terms of complexity, that is much harder overall. Americans could achieve everything in their F-22 (it is stealthy, fast and highly maneuverable), but looking on F-117 you may imagine long way they took. Although the later you start, the easier it will be. Creating F-22 20 years ago is much more complex task than creating this today, just because technology slowly flows into common military and civilian market.

> and even those how many of them in service, one?

One if you are strict (F-22), two if F-35 counts. Personally I think that F-35 is a great and unique plane that people hate for silly reasons, although it isn't "pure" 5th gen.
