Yes, those polygons which have angles of 90 degrees and equal side lengths are called squares; those with uneven side lengths are called rectangles.

Rectangles and squares are the only ones.
A square has 4 interior right angles; 2 squares therefore have 8 angles.
Certain quadrilaterals have right angles. Right trapezoids are the most general example. Rectangles are specialized right trapezoids, and squares are specialized rectangles. There may be more but I can't recall them. Many rhombuses and parallelograms have no right angles. However, they might (and then you'd probably call them squares or rectangles but they are also technically rhombuses, parallelograms and trapezoids).
No, only squares and rectangles have 4 right angles.
They are a square and a rectangle
