yes
There will be two pairs. It is possible for all four angles to be identical.

All regular polygons have equal angles; so an even numbered regular polygon will have a whole number of pairs of equal angles.
A Rhombus.
Whenever two lines intersect, vertical angles refers to the angles opposite each other
No, vertical angles are not always supplements of each other. Vertical angles are formed when two lines intersect, creating two pairs of opposite angles that are equal in measure. While they are congruent, they are not supplementary unless they specifically measure 180 degrees together, which is not the case for all pairs of vertical angles.

which pairs of angles in the figure below are vertical angles
There will be two pairs. It is possible for all four angles to be identical.
You are describing a rectangle. A rectangle has two pairs of parallel sides, opposite sides that are equal in length, and all angles that are equal (each measuring 90 degrees). It also has two lines of symmetry: one vertical and one horizontal.
ISN and TSW TSN and ISW
No, unless they're all right angles. Otherwise it has two pairs of equal angles.
Never. A rectangle has 2 pairs of equal sides and four right angles whereas a rhombus has all sides equal and 2 pairs of equal angles.
Never. A rectangle has 2 pairs of equal sides and four right angles whereas a rhombus has all sides equal and 2 pairs of equal angles.

A rectangle.If all four sides are equal, then it's a square.
Diagonally opposite pairs of angles will always be equal, but the only time all angles in a quadrilateral parallelogram are equal is when that shape is a rectangle.
