Biruchi: Maybe with an emulator? It is the only way?
teceem: Have they been released for Windows/Linux/MacOS/XBOX360? If not, what other way would there be?
That first game, Kameo, are you sure it exists for the original XBOX? I can only find an XBOX360 game with that name.
Anyway, good luck! Little effort has been put into XBOX emulation... because most/best games for that console were multi-platform. "good/best" is of course subjective, so maybe the games you like might never be available emulated.
I can't help you with my experience, but here's a list of emulators:
https://emulation.gametechwiki.com/index.php/Xbox_emulators A lot of effort has been put into XBOX emulation, but the lack of available documentation and it essentially being a Pentium CPU, it's proven to be very difficult to emulate. The power required, even on modern hardware, is also currently a stalling factor.
