2. Notarized translation
3. First certified diploma, then apostilles, then translation
4. First certified diploma, then translation, then apostilles.

Answer 1

English, definitely

Answer 2

The concept of most countries is relative. Some don’t require translation at all, and a diploma too. Why do you need a translation?
If you look at Europe, then usually a translation into the official language of the country is required.
