a) A dimension is a plane of existence or an aspect of a feature i.e. a shape or situation
b) A universe is everything that exists, it also includes itself
We experience four dimensions (length, width, height and time), but some theories (M-Theory) suggest 11-dimensions.
The geometry of our physical universe is three-dimensional.
Answer2:
a) The geometry of our Universe is four dimensional; one real dimension r=ct and three vector dimensions v= Ix + Jy + Kz. This is called Quaternion Space, the sum of a scalar or real and three vectors.
A point in our Quaternion space is p= r+ Ix + Jy + Kz = r + V = [r,V].
Relativity Theory Space-time is x + y + z + ict, this is not a four dimensional space.
)b A universe may have many dimensions. Many Universes differ from many dimensions because a Universe is different from a dimension. A dimension is a direction and a universe is not a direction.
Many universes refer to the existence of multiple separate and distinct cosmic structures that may have different physical laws or properties. Many dimensions, on the other hand, typically refer to additional spatial dimensions beyond the three dimensions of space and one dimension of time that we experience in our everyday lives according to theories like string theory or M-theory.
In the context of a multiverse theory, it is possible to speculate about the existence of other universes beyond our own. These parallel universes may have different physical laws, constants, or even dimensions, leading to a diverse array of potential realities. However, such ideas are currently purely theoretical and remain speculative without any empirical evidence to support them.

There is currently no scientific evidence or consensus about other universes existing within our own. The concept of multiple universes, known as the multiverse theory, is a speculative idea in cosmology and theoretical physics.
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.
We don't know. Spatial dimensions higher than three can only be derived mathematically, but we have no concrete evidence higher dimensions exist, and as limited three dimensional beings we are unable to perceive or experience them. According to string theory, there are ten spatial dimensions plus time.
Geometrically speaking, man knows of three dimensions; height, width, and depth. As far as dimensions with reference to different universes or plains of existence goes, they only currently exist in theory.
Many physicists believes that upper-dimensional travel is a theoretical plausibility. There are theoretical wormholes created through the 3rd, 4th, 5th, and 6th dimensions which in theory should be traversal. Although, humans would probably not survive a travel through the 7th, 8th or 9th dimension, due to the alternate physical rules of other universes.

Mathematically, you can have as many dimensions as you want. Our "real world" seems to have only 3 dimensions. While there are speculations that other universes - or parts of our Universe - may have more or less dimensions, for now, these are just speculations. According to string theory, our Universe actually has 10 or 11 dimensions, but only 3 of those appear on a large scale - the others will only have an effect on very, very tiny scales.
Static Dimensions are dimensions taken when the body is in a fixed (static) position. They consist of skeletal dimensions (between the centers of joints, such as between the elbow and the wrist) or of counter dimensions (skin surface dimensions such as head circumference. Many different body features can be, and have been, measured.
Well, there is a formula to figure out how many combinations of universes there would be that fit in the size of the observable universe. The formula is spacetimeatoms*elements and by working this out you would get 10 to the 225 power, factorial.

Parallel universes fall under the study of Quantum Physics.
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.
