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.
All squares have TWO SETS of opposite, parallel sides. A square is a parallelogram with 4 equal sides and 4 equal angles (right angles) of which adjacent sides are perpendicular. The related parallelogram, the rhombus, or "diamond" shape, also has 4 equal sides, but no right angles, where opposite angles are equal and adjacent angles are supplementary (sum to 180 degrees).

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 parallelogram, rhombus, or diamond, because a square would have FOUR right angles.
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.
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.
All squares have TWO SETS of opposite, parallel sides. A square is a parallelogram with 4 equal sides and 4 equal angles (right angles) of which adjacent sides are perpendicular. The related parallelogram, the rhombus, or "diamond" shape, also has 4 equal sides, but no right angles, where opposite angles are equal and adjacent angles are supplementary (sum to 180 degrees).
