I don't know exactly why, but they simply accepted the № symbol for "number" in Russian. Maybe it's because it was used in German and French, and German was the science and medicine's language in Russia during 18th-19th centuries, while French was the language of the nobles (some Russian nobles hardly spoke Russian at all) and educated people. BTW the № sign itself is just the graphic abbreviation of No., "numero". It has been used in English as well.
Just a tradition. I think wolk_off is right: it appeared in Russian at the times when we hardly had any scientifical or even semi-scientifical terms and used German and French instead.
No, but you'll often find that they speak some other 2nd language (sometimes a 3rd or 4th as well). They teach language at a much younger age than we do in the states. My host mom spoke passable German and my host brother at 9 had already had three years of German.

№ is like that.
