Presuming our geometry is Euclidean, such a shape would be a rectangle, since all 4 angles would be right angles.
If our geometry is hyperbolic, it would be possible to construct such a quadrilateral which is not a rectangle (and in fact, rectangles cannot exist in a hyperbolic geometry). I do not believe such a quadrilateral has any special name.
A square is a four-sided shape with all sides equal and all angles equal.
No shape has four equal sides and four different angles - either there are two pairs of equal angles, or all four angles are the same; or all sides are not the same length.
A parallelogram.
A shape with six sides is a hexagon. A hexagon with all sides and angles equal is a regular hexagon.
square
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.
A square is a four-sided shape with all sides equal and all angles equal.
A shape with 4 right angles and 4 equal sides is a square. ==========================
No shape has four equal sides and four different angles - either there are two pairs of equal angles, or all four angles are the same; or all sides are not the same length.
When all its sides and angles are equal.
As long as the angles are all equal as well then it is a regular shape.
You don't tell us enough information. In a square, there are four sides and four angles. The sides are all equal and the angles are all right angles. In a rectangle, there are four sides and four angles The opposite sides are equal and the angles are all right angles. There is no other shape in which all angles are right angles.
A hexagon has all six sides in equal length and all angles in equal measure.
A parallelogram.
A shape with six sides is a hexagon. A hexagon with all sides and angles equal is a regular hexagon.

A three dimensional shape (triangle) in which all the sides and all the angles are different is called an "Scalene Triangle" There are 3 types of triangles: 1. Equilateral triangle - all 3 sides equal all 3 angles equal (i.e., 60 each) 2. Isosceles triangle - 2 sides equal 2 angles equal 3. Scalene triangle - no sides equal no angles equal
