It's not important, I'm not trying to justify that show's version of time travel because it's nonsense and makes it up as it goes along, but what I'm trying to get at is the subtleties of how you define these various terms. Does literally every universe stem back to the one universe with a Big Bang divergence point, and ever since then events have split and split and split into more and more splitting universes? Or do different parallel universes each have their own Big Bang and tree of events? Essentially, if you think of the branches like a tree, is the multiverse one big tree, or is it lots of thinner trees side-by-side? Which would mean branched timelines within each universe. But yes, it does seem odd to think of a universe with branched timelines, so maybe each branch on the tree is defined as a "universe", and each tree is a "reality", so there's a "reality" with lots of different branched timelines/universes, and "timeline branch"/"universe" can be used interchangeably - then the multiverse is made up of realities, which are made up of branched timelines/universes, which each have their own various dimensions.. Yeah, things can get quite complicated and messy if the whole thing with the Multiverse isn't handled carefully.

For what it's worth, the Marvel Database wiki has already provided seperate TRN (Temporary Reality Numbers) designations to each timeline that the Avengers jumped into, including the one where Captain America married Peggy.

In terms of how the Multiverse works, it's generally shown that there are two ways for alternate realities to emerge: Either naturally with no deliberate outside action (i.e. in one universe, you decide to put your right shoe on first, which results in another universe being created in which you choose to put the left one on first instead) or through time travel.

Spider-Man once even made use of this fact when, during a time travel incident, he asked his younger self for help and told him numerous things about the future in order to have things turn out better for his counterpart.

The Multiverse pretty much is one big tree with numerous ever-growing branches. There is also a distinction between different dimensions and alternate realities. The Dark Dimension, for instance, is still located within Earth-199999, as other realities have their own Dark Dimensions with their own Dormammus.
