There has been some speculation about alternate universes, perhaps some of them with more or less than 3 space dimensions, and even with more than one time dimension, whatever that means. There is no evidence either for or against such universes; it is simply unknown whether there are any such universes.
A 2-dimensional figure can have any number of sides more than 2.
Any photo that isn't a 3-dimensional photo is a 2-dimensional photo.
It can be any 2-dimensional figure.
A plane is 2-dimensional, and has infinite extent in any direction.
no, paper is actually 3 dimensional because it also contains a width of probably like a micrometer or a nanometer. No objects in this universe is a 2 dimensional figure because it will always have a length, width, and height, no matter how small. if it was to be on a piece of paper, than it could be considered 2D.
any flat shape eg:rectangle,circle
Any 2-dimensional shape can be folded to form a 3-d shape. For example, any work of origami.

You cannot. A 2-dimensional floor has no thickness and so would not be able to hold up any weight.You cannot.

Objects that are not flat are any 3-Dimensional objects. A 3-Dimensional object has volume, where as a 2-Dimensional object does not. Examples of 3-Dimensional objects are sphere, cube, and cylinder.
There are none.A square is a 2-dimensional object and so there cannot be any 3-dimensional objects in it.
The set of Pythagorean triple is three dimensional and infinitely large.
