Yes. An ellipse (oval) has two lines of symmetry, but not a rotational symmetry. A parabola has one line and no rotation.
Rotational symmetry counts how many times a shape will fit onto itself when it is rotated 360°. When an oval (I assume you mean an ellipse) is rotated it will fit onto itself after 180°, thus it has rotational symmetry (of order 2).

There is no such thing as 8 lines of symmetry. A circle, for example, has infinitely many lines of symmetry.
