Does not the string theory and others like it incorporate several dimensions to explain their exsistence?

String theory postulaes the existnce of more than 10 dimensions, certainly, but they haven't been proven to exist.

Relativity describes "4-dimensional" spacetime as being curved in a fifth dimension, rather convincingly. If I may oversimplify, m-theory only works in 11 or 27 dimensions, for pure-math reasons.
I am a one-dimensional person so I really can't picture what you're talking about though.

The answer is no.
Many other theories in theoretical physics, such as the various string or brane theories, propose plenty of other dimensions, such as the 10th or 11th. However, none of these have been proven, so in all actuality, there are only four confirmed dimensions.

I don't think we can prove the existence of more dimensions simply because we cannot perceive them. That doesn't mean they don't exist.
What would a three dimensional object look like in a 2 dimensional universe? If you can come close to imagining that, maybe you can start to see the problems in proving more dimensions.
I'm not sure you have to be able to move in every dimension, but you sure have to be able to perceive it's existence somehow.

No.
Every extra-dimension theory to date (including string theories of various sorts) which has had testable implications has been disproven. The only ones still standing are those with no testable implications (or that can't be tested yet and are just waiting for the next generation of accelerators to disprove them).

A dimension is practicly an axis, the first being 1D or one axis ,being able to move 1 direction, forward or backward. 2D being having 2 axis, being able to move 2 directions, forward or backwards, and 3D having 3 axis being able to move in 3 directions, forword or backwards in ether direction.
The fourth dimention is a bit more theoretical but feasable, its being able to move in 4 axis or directions: 3D space and time ( as in like a timeline, like a 3D axis layed on top of each other)

Slow down there cowboy, you still haven't proven the 4th dimension.
For a dimension to BE a dimension you have to be able to move in BOTH directions of it.
Otherwise it isn't Really a dimension.

Yes, there is a fifth dimension and I can prove it because I am currently in it...

11-dimensional space time, yeah baby yeah!
