How to know my ranking level on candy crunch and who is a higher level

Noor

Is't my ranking is the 1st or what? My level now is 3215. I can't see, my friend.

The only ranking that you can view now is the leader board when you finish a level.  It will show you where you placed and who else cleared it and where they placed.  

Regarding not seeing your friend are you looking for her on the map?  Since King changed the version you can no longer see your friends all over the map.
