Rotational symmetry refers to symmetry of the figure when it is rotated about a single point in the same plane. Lines of symmetry apply to reflections. You do not have lines of rotational symmetry.
Yes. A circle has infinitely many lines of symmetry and it also has rotational symmetry of infinite order.

I believe that an octagon has 16 lines of symmetry.
None - it has rotational symmetry - not reflection symmetry.
Rotational symmetry is based on points of rotation not lines

how many lines of symmetry has an equilateral triangle

None.
None.
A regular hexagon has 6 rotational symmetries (rotational symmetry of order six) and 6 reflective symmetries (six lines of symmetry).

None. For a 3-dimensional object, a line of symmetry implies rotational symmetry and an aircraft has no line of rotational symmetry.
