I'm not 100% sure on Airplay. No Apple devices here to test with.
The Q5 doesn't support it out of the box and I don't think that there are apps available that would do what you want. It's an Apple vs Google incompatibility problem, Apple don't want Airplay to be compatible with non Apple devices.
Saying that, if you install Kodi (http://kodi.tv/download/) then go System - Settings - Services - Airplay and turn on 'Allow Kodi to receive Airplay content'. That should work.
