What iOS level is being used on the client's iPad 1? The iPad 1 can be updated to 5.1.1.
What iOS 6-only feature are you using? Why?
It probably would be best to make your App iOS level-aware or implement to an iOS level that can be used on all iPads.

That depends on you entirely, you can set the App requirements when you create it. Unless you specifically set something that requires iOS6 for some reason, it should run on iOS 5.
For more detailed answers you should use the programming forums, as these are for User support only, and not for development.
