A plane figure is one that is entirely in one plane. One way to think of that is it can be made to lie flat - no ups or downs.
A closed figure is one where you can go around the outside of the figure and return to your starting point - without jumping. If you take any two points - one inside the figure and one outside, then you cannot draw a curve from one to the other without crossing the boundary of the figure.

No. A square is a plane figure and conventionally for plane figures symmetry is considered in terms of rotation about a point or an axis (in the plane of the figure) but not a plane outside the plane of the square.
