Parallel universes may, or may not, exist. While it is hypothesized that there may be other universes, there is no certainty that they do exist - nor, for that matter, is there any certainty that they DON'T exist. Since we don't know whether such "ohter universes" exist, we don't know what they look like either - although it has been speculated that other universes may have a different number of dimensions, or there may be other significant differences in physical laws, compared to our own universe. If this is the case, most such universes may be unsuitable for any sort of life.
It is thought that there are other universes that look like ours. It is also been suggested that there are an infinite number of universes.
The idea of multiple universes is, like many other things, a theory. It could be true, it could not.
This is just possibility, considered by some. It may answer the question, why our Universe has specific characteristics, some of which look like it is specifically fine-tuned to permit life: if there are multiple universes, others will have different characteristics, even a different number of dimensions - and out of this multitude of possibilites, a few universes have conditions suitable for life. There is no evidence for other universes, and if they do exist, it is not likely that we can have any contact with them.This is just possibility, considered by some.

That is unknown. Some hypotheses based largely in mathematics have suggested that this is possible, but there is no direct eveidence that other universes exist.
There has been a lot of speculation about other universes, but it is just that: speculation. There is no firm evidence that other universes actually exist. Nor, for that matter, is there any firm evidence that other universes DON'T exist.
'Multiverse' is an abstract noun because by definition it is purely hypothetical. It suggests the possibility of other universes and by definition we could never physically interact with other universes even if they exist. Other universes are not perceptible to our senses. They are physically disconnected from our universe.

"Impossible."
That's related to the idea that there are other universes, other than the one we are in.
The term 'multiverse' is often used to describe multiple universes, or sometimes, 'meta-universe'. Owing to the paucity of proof of the existence of other or alternate universes the term is considered to have only hypothetical application at this time.
What "other universes"? There is no clear evidence that such "other universes" even exist. If they do exist, it would likely make no sense to speak about how old they are NOW. Even within our own Universe, it doesn't make sense to speak about "simultaneity" between far-away points; this means that the word "now" is not clearly defined!
According the the Multiverse Theory, our universe exists as a bubble among a plane of countless other universes, though that's not the limit to how many there are. This plane, which contains many universes, is just a bubble itself, floating in a sea of other bubbles. This sea is just a bubble, too, on a plane of other bubbles, each containing planes, seas, bubbles, planes, and bubbles. According the the Multiverse Theory, there are an infinite number of other universes.
