A, a triangle
That would be a trapezoid. A trapezoid does not have to have two right angles it only needs to have two parallel sides. There is not a name for the exact quadrilateral you are looking for but the shape is still within the definition of a trapezoid.
A rectangle has four right angles. A square also has 4 right angles, but it is a only a square and not a rectangle if all of the sides are congruent.
If all adjacent angles are congruent, it can only be a rectangle (or square).
Quadrilateral. No other special name. A kite could have 1 right angle - that's possible, but there is no special name for a quadrilateral with only 1 right angle.
Rhombus and a trapezoid A trapezoid may have a right angle and a square is also a rhombus, so the kite is the only quadrilateral that can't have a right angle.

A Rhombus
none
A trapezium or a kite.
Square
No you can have up to four, but that's it.

If you are saying a quadrilateral that only has two right angles I believe it is a trapezoid. A square or other rectangle, all of which have four right angles, also satisfies all the conditions explicitly given.
yes it is possible
Trapezium (only type)
A quadrilateral can only have either 2 right angles or four. As you may (or may not) know, the angles in a quadrilateral must add up to 360 degrees. If you have 3 right angles that adds up to 270 degrees, so the last side must also be 90 degrees.
