The three cabins with balconies are identical and all are covered. The decks on the Oasis and Allure are not tiered. Go to Google images and enter "allure of the seas balcony cabin" and you'll see plenty of photos. These are very small balconies.
You didn't say so but I assume you know the first three cabins you listed are insides. Actually I can't find a cabin 7472 in the deckplan.
