If you mean on opposite sides yes. There are 2 pairs of congruent angles.
a parallelogram
A rhombus always have 2 pairs of congruent angles, yes.
A rhombus (pushed over square) will give you 2 pairs of parallel, congruent sides, 2 acute angles and 2 obtuse angles.

a parallelogram
a trapeziod
It has 2 pairs of parallel sides and the opposite angles are congruent.
A parallelogram has the 2 pair of opposite congruent sides, but a rectangle (special case of parallelogram) also has the four congruent angles.
The definition of a rectangle: A figure that has 4 right angles, has congruent diagonals that bisect, has 2 pairs of parallel sides, and has 2 pairs of opposite congruent angles. A square has all of the above, and thus, is a rectangle by definition.
A rectangle has 4 congruent angles. 90 degrees. It is also a parallelogram, 2 pairs of congruent sides.
It could be a hexagon which is stretched out so that one pair of opposite angles become acute - but they must be different otherwise you will have three pairs of parallel sides.
This is a parallelogram. The first requirement is 2 pairs of congruent sides where the congruent sides are not adjacent. This is like a rectangle (excluding a square) that has two pairs of congruent sides where the congruent sides are not adjacent. But the angles are not all congruent (as set in the question) which pushes the shape into the "next less regular" shape, the parallelogram. The angles will not all be congruent, but it will have 2 pairs of congruent angles. There is no way to avoid the 2 pairs of congruent angles because of the requirement that the shape must have 2 pairs of congruent sides (the first requirement).
