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
If they are straight lines, then one solution.
3 lines and one plane
You did not specify if these are straight lines. If the lines are straight then no, only 7. If you curve the lines then, yes.
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.
there are 5 straight lines
No, polygons are made of straight, non-overlapping sides. An ellipse has curves.
Ellipse.
An ellipse has two lines of symmetry.
