Yes
if a quadrilateral has three right angles will also have have a fourth right angle. Making it a rectangle. The addition of all the angles in a triangle is 360 degrees. If there are three right angles, and you subtract their addition by 360, you will get ninty degrees.
A parallelogram with at least one right angle
any regular quadrilateral will have at least one pair, this includes, but is not limited to, square, rectangle and parallelogram
No, a quadrilateral does not necessarily have any right angles. If it has a right angle, it will necessarily have four right angles, and will be a rectangle. But not all quadrilaterals are rectangles. As long as a polygon has four sides, it is a quadrilateral. It might have, for example, two angles of 100o and two angles of 80o.
a square
Yes
It could be a kite, an arrowhead or an irregular quadrilateral with a right angle - which has no specific name.
Any quadrilateral in which at least one (and therefore at least two) angles are not right angles is not a rectangle. The majority of these do not have a specific name.

No.
A rectangle or a square.
Not possible... The internal angles of a quadrilateral always total 360. If you MUST have an angle of 90 degrees - the remaining angles must total 270. At least one of the remaining angles will always be obtuse.
A parallelogram with at least one right angle
Here is how the word, "Rectangle" is broken down: 'Rect' is from the German for 'Right', which in geometry means 90 degrees. And angle is just angle. Together the are 'Rectangle. All 4 angles in a rectangle or 'right', or 90 degrees.

A right triangle or a rectangle are polygons that have at least one right angle. There are other quadrilaterals and many irregular polygons that could have at lease one right angle, too. Many of them. Note that a polygon is any planar figure constructed of a finite number of line segments to make a closed figure. By that definition, which is a correct one, the triangle and rectangle are polygons. And a quadrilateral (of which the rectangle is special case) can be constructed with just one right angle, though it will be a bit quirky looking. Once we start adding sides to make different polygons, the game is afoot because so many possibilities exist.
