rhombus
Adjacent angles will be right by each other and equal 180 degrees. Vertical angles will be opposite and equal to each other.
All squares have TWO SETS of opposite, parallel sides. A square is a parallelogram with 4 equal sides and 4 equal angles (right angles) of which adjacent sides are perpendicular. The related parallelogram, the rhombus, or "diamond" shape, also has 4 equal sides, but no right angles, where opposite angles are equal and adjacent angles are supplementary (sum to 180 degrees).

Yes, two right angles can be adjacent to one another. In the letter "T", it's formed by two adjacent right angles.
Only if the angles formed are right angles otherwise they form vertical opposite equal angles
Adjacent angles will be right by each other and equal 180 degrees. Vertical angles will be opposite and equal to each other.
A rhombus has 4 equal sides but no corner right angles
A square.
All squares have TWO SETS of opposite, parallel sides. A square is a parallelogram with 4 equal sides and 4 equal angles (right angles) of which adjacent sides are perpendicular. The related parallelogram, the rhombus, or "diamond" shape, also has 4 equal sides, but no right angles, where opposite angles are equal and adjacent angles are supplementary (sum to 180 degrees).
Adjacent angles are angles right next to each other
Yes, if they intersect at right angles.
Yes, two right angles can be adjacent to one another. In the letter "T", it's formed by two adjacent right angles.

A Quadrilateral Kite!
Only if the angles formed are right angles otherwise they form vertical opposite equal angles
A rectangle is the only such shape. Not sure about the "little" right angles: all right angles are of the same measure.
A square because a parallelogram has two parallel sides and have two adjacent right angles but a square and a rectangle have also a two adjacent right angles.
