the answer is a square * * * * * No. It is equilateral. An equilateral triangle, or a rhombus are shapes that have equal sides, but neither are a square. The answer is not a regular polygon since that also requires equal angles. A rhombus is equilateral but it is not equiangular and so not regular.

Square
The most precise name for a shape that is both a rectangle and a rhombus is a square. A square is a quadrilateral with four equal sides and four right angles, meeting the criteria of both a rectangle (opposite sides are equal and parallel, and angles are right angles) and a rhombus (all sides are equal). Therefore, a square is the most specific term to describe a shape that is both a rectangle and a rhombus.
There is no special angle and so it does not have a specific name.
Yes, the common name for an equiangular equilateral quadrilateral would be a square, a special instance of a rhombus (four sided figure with equal sides) which is a common interpretation of "diamond" in two dimensions. If by diamond you mean "kite" then no, by definition kites are not equiangular.
Rectangle.
Any quadrilateral that is not a rhombus (or square) although there is no specific name.
Rhombus is the geometric name.
Rhombus, or square if there are any right angles
the name rhombus came from German languages
I don't use the name "rhombus-quadrilateral", but perhaps the answer to your question is that a rhombus is a special kind of parallelogram
