Foreign Air Force badges

[billy]

Hi here is a few badges just seeking clarification on them:-

1st I believe is Greek with blue enamel, seen another with a plain globe, was this WW2 era?

2nd Pakistan Air Force, when this is from I hope someone might know independence was 1947 so after that?

3rd I am guessing at Rhodesia Royal Air Force, but can't find on google?

Many thanks in advance Billy
