And if the bubbles weren't all get spawned in the same event, then it is very likely there were bubbles spawned before our bubble just like after our bubble, in whatever context of "before" and "after" you wish to define. Just because it is in a different coordinate system doesn't mean there isn't a framework of before and after within that system.

Call it "time prime" or something.
Sure, so if we define our universe with 4 dimensions--x, y and z for space and t for time, then mathematically it's easy to just keep on adding new axes that are orthogonal to x, y, z and t. So we could call the distances between our Universe and some other Universes q, r, and m or whatever.

The problem with defining these relations is that we have no evidence for the physical existence of other universes, let alone some method of investigating the differences between them. But in any case, another universe wouldn't be north of our universe, or left of our universe, or before our universe. But you're right that it might help us to envision some relations as analogous in certain ways to time or spatial coordinates. Or maybe some other analogy would be more helpful, like our universe is cinnamon and theirs is chocolate and another is strawberry.
