Jenny,
They all look wonderful and the one with unopened bloom should be fine. Sometimes the blooms take quite awhile to open. Especially if they are triple or quad petaled blooms.
Transition with moving, different environment can effect grow and blooms, but I doubt this will be an issue for yours.
I have a friend in Australia and a wonderful woman, Sandy.
She grows amazing Adeniums and has a website. Super friendly person and always helpful.
