Fish addition order

[LJA]

Hello. Been out of the hobby for a long time and wanted to ask about new fish timing since some of these I never had before.

Do all tangs have to be added at the same time? I want to add: Yellow, purple, hippo or powder blue

Flame angel

Ocellaris x 2 (already have one mature one from a different tank, will be adding a second)

Anthias harem 1 male 2 female (open to several specied choices, leaning towards lyretail) All need to be added at the same time right?

Any issues with the above selections? Any particular order they need to be added?

Tank is a RedSea 450

I dont think so. I would add the tangs at once but if they are small ones it doesnt really matter. You can get 3 female anthias and one will change to male.
I much prefer a powder blue over a hippo tang.
