Hi,
I remember that Winamp was able to play Fasttracker2-Files,
is there a plugin for .rns-files??

No, currently not.
Such a plugin would not make any sense because maaany renoise-songs rely on vst-plugins. So, that plugin would need to have the ability to load vst-plugs again 
And the user must have those plugins as well.
More important might be that renoise has a lot of onboard effects which did not exist in FT2. I guess this would make a huge Plugin
