3, or perhaps more. It depends on the theory to which you ascribe. For example, recent research done at the Princeton Institute for Advanced Studies (IAS) led to the creation of ekpyrotic theory. According to ekpyrotic theory, our universe and its creation stems from the collision of two "branes" that could theoretically and literally represent parallel universes. According to Julian Barbour, an infinite number of parallel universes exist, since every time a decision is made on either the microscopic or macroscopic level, a bifurcation is created leading to the birth of a new "universe". Long answer short, minimally 2 parallel universes, maximally infinit.
Eleven dimensions have been postulated, mathematically, by string theorists. Multiple universes have been postulated to be probable, even highly likely - even an infinite number of universes. Then there is the concept of the multiverse.
there is only one the universe is what contains everything in space
Currently the concept of a multiverse is a purely speculative hypothesis. There is no way of knowing whether or not there is a multiverse, let alone home many universes it could contain.
Parallel Universes are a theory.
There was never a big bang until around 10,000 years after the world began this created parallel universes but the laws of gravity are different because of illusions. every 10,000 years there will be a bang to create new parallel universes
Theoretically, there are infinite parallel universes in the multiverse, however it is not necessarily widely accepted that the multiverse exists.
Certain cosmological theories such as the brane therory include many "universes" although properly, by definition, the Universe is everthing; so they might be called "multiverses"
There is no evidence that Parallel Universe exists, but doesn't mean that it doesn't exist. Accord of the law of Physics, yes Parallel Universe can exist. However if Parallel universe does exist, it will benefit to because when our universe come to an end, the only way to survive is to escape our universe to parallel universe.
Scientists admit that there may be as many as 27 'parallel universes' to our own. It is quite possible that there is not only an antimatter universe, but parallel universes to it.

As far as we know, there is one Universe. There are hypothesis about parallel universes, but for now, there is no way to confirm that.

In theory there are a infinite parallel universes, one for each possibility.
According to some cosmological theories, there is not a single universe but several - even infinitely many - universes. However, they are diverged at the Big Bang and the start of time. It is, therefore, unlikely that anyone will ever be able to find a parallel universe, much less travel to it.
That isn't currently known. There are several ideas about multiple universes, but in many of those ideas, the other universes would not be "before" or "after" (for us, time itself starts when our Universe begins), but in parallel, so to speak.
Parallel Universes are a theory.
Parallel Universes - film - was created in 2001.
Some cosmological theories predict the existence of not just one universe (our own) but many - possibly even infinitely many - universes (or multiverses). However, since they were all created in the Big Bang, these theories also predicts that no information can escape from those universes to ours. If that is true, then we cannot know.
there many universes apart from us, so there are many universes outside our universe and dark matter are the things that hold our universe and other universes. There is also a theory that explain dark matter is just mass that is from another universe which would be our parallel universe, i know it sounds mad, it sounds crazy, but that is the law of physics. But there really is no explanation yet, there is a whole shelf of Noble Price waiting for people to come up with the correct explanation of what dark matter really is.
According to some, there are infinite parallel universes. (String theory) However, in the sense of our perception of space, no.
