The entire universe is but a point inside three dimensional time. That is how I comprehend it anyway, so if you could perceive time you would see our universe as a string that only occupies space along the zt axis. The habitable universes would be represented by a slightly thicker noodle that encompasses our perceived universe.
I have seen some two dimensional imaginings of four dimensions and I must say I honestly don't understand them.

You've gone fundamentally wrong in one key area, you have placed time outside the universe.
Time as we know it (as a dimension) was created in the big bang with space, matter and energy. The big bang did not explode into space-time, rather it expanded bringing space and time with it. As such time is a single dimension within our universe, each 'alternative' or 'parallel' stream of time is not an instance within our universe, but instances of entire universes with their own single dimension of time inside a higher dimension that, if you were able to perceive, would allow you to see time as if it was a tree, for lack of a better analogy.
