Two, going top to bottom, and left to right. You can't go diagonal because the sides will be hanging over another. Extra will hang over and it has to be perfect to be a line of symmetry.

Put more simply, 2 axes of symmetry, and they are the major and minor axes of the ellipse.

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).
