A circle is not a 3D figure because it only has two dimensions. A sphere is a 3D "circle".
A parallelogram is a two-dimensional figure, so it has two dimensions.
A plane figure has two dimensions !
It's any figure that you can draw on a flat piece of paper or carve into your desktop.

No, the sun is not a plane figure. It is a 3-dimentional astronomical object we call a star. Plane figures have just two dimensions.
A cm is a 1 dimentional measuring unit and squared meter is 2 dimentional measuring unit. As they belong to two different dimensions, they cannot be compared.

They can be three dimensional, for example, the Menger Sponge. Mathematically, there is no limit to the number of dimensions.
It does not measure anything. It is a two dimentional figure equivelent to half of a circle.

A pentagon is a polygon that has 5 sides. It is a planar geometric shape made of 5 line segments, and by definition, the shape lies in a plane. It has only two dimensions. In the two dimensions of the plane, the pentagon has five sides. By adding a third dimention to view it, it still has only five sides because it has no "thickness" owing to the fact that it is a geometric figure confined to a plane. In either a two domentional view or a three dimentional view, the pentagon has 5 sides. Adding another dimention to view it will not "add any more sides" to the pentagon.
