Question

can I say "duh" as well as "yes" or "of course"  in spoken English?

Answer

I concur with Sharon's answer.  Responding with "Duh" is quite insulting as it implies stupidity.

Answer

I also agree with Sharon that to a closer friend this may not be rude, but otherwise it would be. Even with friends it can depend on tone of voice.

Answer

'Duh' is a very sarcastic equivalent to 'of course', implying that the remark you are responding to was so obvious as to be completely stupid.  You might get away with it to a close friend, but to anyone else it could appear fairly rude.
