Don't see any pics or videos in your post. I keep multiples of each coral you listed in my reef.
All of my Favias and Bubbles extend some pretty good sweeper tentacles at night. I'd definitely recommend giving them some space (though they seem to do just fine with each other in the Favia and Bubble gardens I have).
Elegance corals don't really have that problem, but you'd be shocked how much flesh and polyp extension they can get out of a 3-4 inch skeleton. And they are sticky, which means their nematocysts pack a powerful punch. Best to give them quite a bit of space too.
