A flag with four sides of equal length is a square flag. An example of a square flag is the flag of the Vatican City, which features a unique design with the Papal Tiara and crossed keys. Square flags are less common than rectangular ones but are used by some countries and organizations for various purposes.
No.No.No.No.
If all the sides are different lengths, it can only be called a quadrilateral. In general, four sided two dimensional objects are called quadrilaterals. When all four sides are the same length it is a square if all four corners are right angles. Otherwise it is a rhombus. If the opposite sides are the same length, it is a rectangle if the four corners are right angles, otherwise it is a parallelogram. In all these cases, the opposite sides are parallel to each other. There is also the trapezoid, a quadrilateral with only one pair of parallel sides. If the opposite sides are the same length but not parallel. it is an isosceles trapezoid.
A square.
Square.
Technically it is because a rhombus is a parallelogram that has four sides of equal length in the same way that a square is technically a rectangle that has four sides of equal length.
A square and a rhombus both are quadrilaterals that have sides that are the same length.

All four sides of a rhombus are equal length.
I am a rhombus. I don't need to prove that my opposite sides are parallel. If I'm a quadrilateral with four sides that are the same length, then I am definitely a rhombus.
No. A square has four equilateral sides and a pentagon has five sides.
If a parallelogram has all four sides the same length it's called a square.
This is called a Parallelogram. Each pair of opposite sides will then be the same length. If all four sides are the same length, and opposite sides are parallel, then it is a rhombus. NB: If all four sides are the same length then the opposite sides must be parallel.

four
A four-sided shape with only 2 sides the same length is called a rhombus.
