Not all 4 sided quadrilaterals have lines of symmetry.
Parallelograms: 2-fold Square: 4-fold n-fold symmetries refer to rotational symmetries. Consequently, any symmetries about axes that these and other quadrilaterals may have are not relevant to this question.
Not all 4 sided quadrilaterals have lines of symmetry although some of them do have lines of symmetry.
No it is not true but all quadrilaterals have 4 sides. But a square has 4 lines of symmetry and 4 equal sides.

A square has 4 axes of symmetry.

No because all triangles have only 3 sides whereas quadrilaterals have 4 sides.
