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
If they are straight lines, then one solution.
3 lines and one plane
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.

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.

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.
Ellipse.
An ellipse has two lines of symmetry.
