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.
No. This is only true of squares and rectangles. Perpendicular means that the sides meet in a right angle. A rhombus has two acute angles and two obtuse angles.
They are equal.
Square & Rectangle are the only two. Rhombus (diamond) & parallelogram have adjacent sides, but no 90 degree angles (not perpendicular).
The angles sum to 90° and the angles are complementary

Generally no. If they are perpendicular, all four angles are right angles and the parallelogram is usually called a rectangle.
All angles in a square are 90o so all adjacent sides are perpendicular to one another.
A kite can have 1, 2 or 3 acute angles.
Yes and they meet at right angles which is 90 degrees
