Can a human SMELL in STEREO? With my eyes I see 3D, with my ears I hear 3D, but my nostrils...

Rats can smell in 3D and pinpointing the location of unpleasant odors.

Well I certainly have a very rough directional sense of smell. So far it has never failed to lead me to my dinner.

Well, you do have two nostrils. I can detect next door's barbecue.

Not really. To get any true stereo effect you need two sensors mounted apart from each other, such as your eyes and ears. A smell might reach one nostril before the other but normally, if you detect a strange smell, you tend to rotate to search for it. You can determine the direction of a smell to some degree by turning your head until you get the strongest signal.
