Thanks for reaching out to the Apple Support Communities! From your message I can see that you have erased the 2011 MacBook Air and are looking to upgrade the OS X from Lion.
You're correct that you need to upgrade to OS X El Capitan before you can upgrade to macOS High Sierra.
Since you're unable to reinstall the Mac OS X Lion through Recovery, see if you can boot into Internet Recovery. To access Internet Recovery, restart your MacBook Air and hold down Option + Command + R. This will allow you to reinstall OS X Lion.
By reinstalling Lion you'll have access to the App Store and you can follow the steps to upgrade to OS X El Capitan: How to upgrade to OS X El Capitan.
Once you have OS X El Capitan running, you can then upgrade to macOS High Sierra: How to upgrade to macOS High Sierra.
