Whole front wall of house, outlets not working / no power
If no breaker is tripped and all gfci outlets are ok, then it is likely that these outlets and fixtures are fed from another outlet or fixture and the connection there is problematic.

It sounds as if you have little experience with wiring, and aluminum wiring poses a special set of issues. Connections between aluminum wiring and copper based devices often are problematic unless special techniques are used to ensure good permanent connections.

This sounds like a project for a professional electrician to trace the break in the circuit and ensure that all aluminum connections are sound and safe.
