Of course it's possible. All hashes, by their very nature, have collisions. The only way to have a truly unique identifier is to use the actual content of the file (or chunk) itself.

That's *AFAIK* not possible, if this would be true the edonckey/emule protocol would have a big design flaw and poeple couldn't even trade millions of files every day, some (most?) downloads would be corrutped as they could have potentialy downloaded a wrong chunk which in fact is from another file.
They are, however, somewhat rare. That's why the system works as relatively well as it does.
Regarding corrupt files via P2P protocols... no file transfered via P2P has _ever_ tranferred bad data and wound up corrupt, right? :) /friendly sarcasm.
