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.
Its a diamond :]
A diamond, a rhombus, or a parallelogram.
A diamond, typically referring to the shape of a rhombus or a geometric figure with four equal sides, has four angles. The sum of the interior angles in any quadrilateral, including a diamond shape, is 360 degrees. In a diamond shape, opposite angles are equal, and adjacent angles are supplementary (adding up to 180 degrees).
A quadrilateral with four equal-length sides and opposite angles equal (but not all four) is a rhombus. That's the usual description of a diamond shape.
That is a parallelogram; it could also be called a diamond shape.

Any regular shaped polygon has equal angles and equal sides
A parallelogram, rhombus, or diamond, because a square would have FOUR right angles.

That is a rhombus, an equal sided parallelogram. It is diamond-shaped.

A shape with 4 right angles and 4 equal sides is a square. ==========================
A square has 4 equal sides with opposite angles that are equal.
A shape where all the sides are equal and all the angles are equal. If all sides are equal but angles or not, it is equilateral. If it is vice versa, it is equiangular.
It can be. A rhombus is defined as having sides of equal length and opposte sides and opposite angles are equal. Generally they are diamond shape but by definition can also be square.
