Can I use silicon spray to lubricate my hybrid cycle chain?
Can you? Yes. It is not optimal for use on chains though. It washes away rather easily leaving your chain unprotected and un-lubricated. It would work in a pinch but a light oil or something specifically made for the application will work much better and last a lot longer. 

Wet or Dry lubes depend on the riding conditions and where you live. WD40 makes a good bicycle chain lube, their bike line, not the generic stuff in a can. Don't use that. RocknRoll, Triflow, ProGold all also makes good lubes.
