Yes, an obtuse triangle can have two congruent angles, where for the obtuse angle measuring A degrees, each of the two other angles measures (180-A)/2.
If 2 angles are congruent and complementary, they must each be 45 degrees.
They have obtuse angles on each side.
None because it has 2 equal obtuse angles and 2 equal acute angles but its diagonals intersect each other at right angles
6 obtuse angles, 120* each 6 Reflex angles, 240* each
The two angles were complementary to each other.

No, complementary angles need to ADD and EQUAL 90 degrees. Supplementary angles need to ADD/EQUAL 180 degrees. They do not necessarily need to be adjacent to each other, they only have to add up... Complementary = 90, Supplementary = 180
The question does not really make sense. Once might ask, "Are consecutive angles in a parallelogram complementary?" in which case the answer is no. Complementary angles are angles which add up to 90 degrees. Consecutive angles are angles next to each other (or follow each other). In a parallelogram, consecutive angles are supplementary (add to 180 degrees). In a parallelogram, opposite angles are equal. You could have a parallelogram where two angles are 45 degree (and thus complementary) and then the other two angles would be 135 degrees.
complementary angles measures add to 90 and supplementary angles measures add to 180. Whether they are next to each other or not does not matter.
equal to each other
If 2 angles are congruent and complementary, they must each be 45 degrees.
With 2 acute and 2 obtuse angles it has 4 angles - the shape is a quadrilateral. The shape can be one of trapezium, parallelogram, rhombus, kite or a general quadrilateral. With the two acute angles next to each other (forcing the two obtuse angles to be next to each other) the shape can be either a trapezium or a general quadrilateral.
They have obtuse angles on each side.
No angle can be complementary to a 140 degree angle, as the sum of complementary angles is 90 degrees. But angles which are supplementary to each other add together to form a 180 degree angle.
