I think apply for one university with AAB, but applying for all five AAB would be silly. AAB universities are not lenient, they are the red brick universities who receive hundreds of applicants with those grades, they don't need to be lenient. And unfortunately, there are no way to hide AS grades (they used to have a system where you only applied with predicts grades, therefore lots of people got offers based on predicted grades despite having poor AS grades)
I think universities more in the range of ABB-BBB would be more safe options and also tend to be more lenient especially universities that require points rather than grades. If you're doing the EPQ this will also work in your favour as universities may let one grade slip for you. But the likes of Manchester, Sheffield, Bristol, Liverpool, Southampton, Surrey.... they won't particularly like the fact that you'll have three pending grades for AS (as this is what you have to put when resitting papers because you don't know your final AS grade currently).
If its any help I'd say apply for
1 AAB
2 ABB
1 BBB
1 BBC
those would be wise entry requirements to apply for as you'd insure yourself as least two offers so if all else failed you could still attend university.
