Only the pair of angles opposite the line of symmetry are equal. The other two angles that are bisected by the line of symmetry are not equal. if these angles were equal then the shape would be a rhombus.
A rhombus has a pair of opposite equal acute angles and a pair of opposite equal obtuse angles and the four angles add up to 360 degrees.
This shape has only one pair of opposite sides and no right angles: <
Unfortunately, that shape is impossible to create. You would need to change one of your conditions to saying "two pairs of opposite sides that are equal" in which case you would get a rectangle. Or, you could get rid of the right angles. But if one pair of opposite sides can be equal and there are four right angles, then the other two sides will also be equal, which contradicts your first condition.
It has two pairs of angles. Each pair of opposite angles is equal.

It has one pair of opposite angles that are equal but not two.

Yes and they are one pair of opposite equal acute angles and one pair of opposite equal obtuse angles. Its 4 interior angles add up to 360 degrees.

A parralelogram
It is a quadrilateral shape because it has 4 sides and it has 2 pairs of adjacent sides that are equal with 1 pair of opposite angles being equal and its diagonale are perpendicular.
Either a square or a rhombus. A square has four equal (right) angles, while a rhombus has two pair of equal opposite angles (one pair acute, one pair obtuse) between the four equal sides.
A kite or an arrowhead.
