None; an ellipse is a smooth curve, not a line.
An ellipse has two lines of mirror symmetry: the line that includes the two foci of the ellipse and the perpendicular bisector of the segment of that line between the two foci.
there are 5 straight lines
3 lines and one plane
If they are straight lines, then one solution.
None.
It could be a stretched circle - a bit like an ellipse except that an ellipse does not have straight lines.
No it cannot. A polygon is a plane space enclosed by straight lines. An ellipse consists of a curved line, not straight lines.
An ellipse does not have four straight lines; it is a smooth, continuous curve defined as the set of points where the sum of the distances to two fixed points (the foci) is constant. While you can draw tangents that touch the ellipse at various points, the shape itself is not composed of straight lines. However, one can inscribe a rectangle within an ellipse that has four straight sides, but that is separate from the ellipse itself.

No it is not. An "Ellispe" is not even a recognised word!. In any case, a polygon is a plane space enclosed by straight lines. An ellipse consists of a curved line, not straight lines.
An ellipse has just one. An oval can also refer to a circle that has been stretched by inserting two parallel straight sections - as in a running track. In such cases, it has two curved lines.
there are 5 straight lines
Assuming a circular cylinder:Cutting lengthwise, you get a rectangle.Cutting parallel to the circular bases, you get a circle. Cutting at an angle, you can get an ellipse - or a shape that has parts of an ellipse, as well as straight lines.
No, polygons are made of straight, non-overlapping sides. An ellipse has curves.
