copy simulator from one mac to another mac osx
As @patrix told me to tried on my own self, I've do so, I got the simulator from here,


  /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs


and copy the simulator sdk you want to add in your xcode, and paste it on the same path as above in your mac. That's it.
