Supplementary angles add up to 180 degrees
Yes. 2 supplementary angles are angles that share a common side and add up to 180 degrees.
They are adjacent angles.
Adjacent angles.
Yes. If the two acute angles have their measures add up to 90 degrees, and both angles share one side that is common to each angle (they are adjacent), then their non-common sides will be perpendicular.

Supplementary angles.
Two angles that share a common side and add up to 180 degrees are called right angles and are 90 degrees.

Adjacent angles.
Yes, 2 angles can have 3 points in common. Two angles of the same number of degrees can be superimposed on each other and would share all points. Or, you could choose 3 points on one line segment, while having two other line segments which do not share points, and which delineate different angles.
Yes, any two angles in a parallelogram that share a common side are supplementary.
Adjacent angles are angles that have the same vertex (corner) and share a common side.
