Can I install OS X Lion Offline on Macbook Air 2011 and Mac Mini 2011?

I know that for the Macbook Air 2011 and Mac Mini 2011, they are using the pre-installed OS X Lion which are having the dissimilar build number (11A2063). But I have read that for the 10.7.2, it having just a single build number: 11C74 . So I was wondering that if I will be able to purchase the Lion Installer from Mac App Store and after that use the same InstallESD.dmg installer offline for Macbook Air 2011 / Mac mini 2011. I a not sure that if this is going to work and so I thought that this will be better for me if I can confirm this from you people once. Please reply as soon as possible.

Yes, there will be no problem to do this. I have also made use of the copy of Lion as of the Mac apps store fro restoring the mba and Mac mini for my brother who was stuck with the restore process. But you must make sure that you are having the legal Lion copy which is downloaded from the store.

It might be possible to do this but it is not legal. It is recommended to have two different copy of that for two system. It is not supported from apple.

Yes, you can do that but you need to have the cracked copy of the installer so that it can be installed on two different devices without any problem.
