Yes. There is no rules against wearing makeup, you can have a full face on if you like.
Yes, they don’t care what u look like, the only thing is that u must be willing to work like a dog and be treated like school children. No phones allowed on shop floor and no talking allowed whatsoever. U also had to ask for permission to go to the toilet or drink some water if u were ill, and u would be forced to stay and finish ur shift if no one could cover u if u needed to go home due to emergencies or illness. That is of course unless u were a favourite of the manager then u have free rein to do whatever.
yes, no issues with makeup.

No they don't not allowed
Yes, I believe so
yes but only a little bit
