No, it is not true that in a polygon all sides and angles are congruent. A polygon with all sides congruent is called a regular polygon, but there are also irregular polygons where the sides and angles can vary. For example, a rectangle has congruent opposite sides but not all sides are equal, and its angles are congruent but not all angles need to be equal in other types of polygons. Thus, congruence in sides and angles only applies to regular polygons.
A regular polygon is a polygon with congruent sides and interior angles.
That's a regular polygon.

Not necessarily. A convex heptagon is a polygon but it need not have all sides and angles congruent.
A polygon with all sides congruent is a square.
