what are the hidden dimensions? what are their names?
how did scientests discover them?

String theory requires more than three space dimensions to be consistent. Superstring theory requires 10 dimensions (1 time, 3 "normal space", and 4 "hidden space" dimensions).
Randall-Sundrum theory (a particular theory within superstring theory) has a different idea. They say our 3-D world is a "brane", a kind of boundary of the higher dimensional world, which they call the bulk. All the forces except one spread out only in our brane. But gravity can spread out into the bulk as well. They use this to explain why gravity is so much weaker than the other forces; it's because its strength is spread out among 4 or 5 extra dimensions.

How about 26 dimensions? IIRC, mathematics in those theories show that only either 11 dimensions or 26 dimensions exists.
Is there any qualitative explanation of what the 26 dimensions are, besides dimensions of time and space ?

Read "The Universe in a Nutshell" by Stephan Hawking. This will help explain multiple universes. But honestly, I still really don't get it. And always remember, it's all hypothetical.

do u mean by (hypothetical) that it is just a theory , a fiction or doesn't have practical uses??

what is that theory that shows that there is 26 dimensions??
is it a really or a fiction??
what r these dimensions?
The eleven dimensions are a theoretical concept in physics that proposes the existence of eleven dimensions in our universe. These dimensions are thought to go beyond the three dimensions of space (length, width, and height) and the fourth dimension of time.
The hidden names in eleven dimensions refer to the different ways in which physicists and mathematicians have labeled and described these dimensions. These names, such as branes, strings, and membranes, represent different theories about the nature of these dimensions.
The concept of eleven dimensions was first proposed in the 1990s by theoretical physicist Edward Witten. It was based on previous theories such as supergravity and string theory. Since then, many scientists have explored and expanded on this concept, leading to the development of the M-theory which incorporates eleven dimensions.
The existence of eleven dimensions is still a theoretical concept and has not been proven. However, many scientists believe that understanding these dimensions could help explain some of the mysteries of the universe, such as gravity and the origin of the universe.
If eleven dimensions are proven to exist, it could have significant implications for our understanding of the universe and could potentially lead to groundbreaking discoveries and technologies. It could also open up new avenues for research and further our understanding of fundamental physics principles.
