Those budgies are beautiful!
They could be rainbow budgies, but I'm not able to tell for sure. Better pics would be needed to have a better look at the cheek patches and their overall body colours and markings.
They both appear to be sky blue in colour and golden face, they are also opalines. I'm not sure if they are clearwings or full body colour greywings.
Hopefully someone better at colour mutations will be able to shed some light.
