First international trip with friends to a country with completely different culture, infrastructure, mentality etc etc. You ought to cut down on un-necessary travelling.
Indonesia is facing an up-hill battle with the virus at the moment. Luckily(relatively speaking) all major diving destinations are outside of Java and Sumatra. But no one can predict what would happen between now and end of 2021.
My vote is also for Bali.
1. It has top side attraction.
2. Diving is diverse.
3. Unless diving in Tulamben(shore dive) otherwise it is usually a boat trip with 2-3 dives.
4. Use Padang Bai as base first and then take the fast ferry to Lombok.
5. Move over to Nusa Penida after returning from Lombok.
Wait until beginning of 2022. It is really pointless at the moment.
For the OP who only has 5 days for diving I would say Tulamben Amed area would be good. If you want 5 days of diving then you cannot plan trips to other areas that also take another day to get to. Last year I had planned Tulamben Amed, Raja Komodo and Lombok but that was on a 24 day vacation where we could take time to travel and see other things as well as dive.
5 days of diving will fly by pretty quickly. Get the best out of it by not trying to travel to too many places.
