If they are the same shapes but differ only in size, then they are SIMILAR shapes. Otherwise, they are simply different shapes.
They are said to be similar shapes and have the same interior angles.
A cube has 6 flat surfaces. Most boxes of all shapes also have six flat surfaces
Sphere, ellipsoid, torus, paraboloid, hyperboloid are shapes with only curved surfaces. Hemisphere, quadrant, cone and cylinder are examples of shapes with curved and plane surfaces. There are, of course, many others.
Yes - even shapes with different area.
Different kinds of solids have surfaces of different shapes.
Shapes have flat surfaces in plane geometry. They can also be described as two dimensional shapes.

A shadow can be called a projection, if you are discussing the way one shape can be transformed into another as a shadow.
Shapes have flat surfaces in plane geometry. They can also be described as two dimensional shapes.
Shapes that are the same except for their size are called "similar".
landforms
They are called polygons.
