Default washer sizes

what are the washer sizes for the

sump plug washer
gearbox drain plug
gearbox filler plug
diff drain plug
diff drain filler plug

I think I've got all of them?

Does it matter if any are copper or aluminium?

Is there any reason they chose copper for just that one? I assume swapping to alum would be fine?

I'm assuming right these are the internal diameter?

You assume correctly, and for reference the OD of the 14mm aluminum one is about 24mm.
