They must have all angles which are the same, all of whose straight lines are in the same ratio and whose curves have radii of curvature in the same ratio.
They are closed 2-D shapes with straight sides.
3-d shapes are not made from 2-d shapes. 3-d shapes may have projections onto a plane that are 2-d.
Yes, there are 4-D shapes, also known as four-dimensional polytopes or "polychora." Just as 3-D shapes are defined in three spatial dimensions, 4-D shapes extend this concept into a fourth dimension. While we cannot directly visualize four dimensions, we can represent 4-D shapes mathematically or through projections into 3-D space, similar to how a 3-D object casts a 2-D shadow. Examples include the hypercube (or tesseract) and the 24-cell.
There is Paper or Card or some other art stuff you have in your home
a cube has parallel faces so does a cuboid and so does a cylinder and also if you want to find out lots more stuff about 3-D shapes or 2-D shapes see the website in the related link

3 dimensional shapes have breadth, width and depth whereas 2 dimensional shapes have only breadth and width

yes
No because isosceles triangles are 2 dimensional shapes.
There are no triangular prisms in faces. Faces are 2-d shapes and these cannot contain 3-d shapes in them.
2d shape is a dimension
No, they have only one face.
