It depends by what you mean by “supported”. All of these models should run just fine in Counter-Strike. The problem is, how to get the game to use them.
For simple props, you could just put them into the map with Hammer.
For weapons, you will probably have to recompile them with proper animations, and set the file name to overwrite one of the existing ones. This only works client-side, though, if I remember properly.
For playermodels, I’m not sure. If they do use the right animations already, you can just get the files renamed to overwrite existing ones. If not, you will have to recompile with proper animations.
One last thing: try to use more descriptive thread titles. We can tell it’s a question based on the “Question” icon right next to it.
