There is no such shape. A 2d shape with 5 sides and all equal angles must be a regular pentagon (or a 5-pointed star if you stretch the definition of "all angles"). And a regular pentagon - or star - has 5 lines of symmetry.
No, all sides are UNEQUAL. Nope, all different. All sides equal would be equilateral which means "equal sides"
A parallelogram where all sides are equal is a square.
Not unless all angles are also equal. A rhombus is a parallelogram with all sides equal. A rectangle is a parallelogram with all angles equal. A square is a rhombus with all angles equal which is a parallelogram with all sides equal and all angles equal.
Square. By definition, its sides must all be equal.

The only shape that always has equal sides and equal angles is the square.Other shapes can have equal sides and angles (like a triangle or octagon), but they are not by definition equilateral.--------I think it is worth noting that any regular polygon satisfies the definition. Conversely, as you point out, you have to explicitly specify that it is regular.

A regular pentagon has 5 equal sides. An irregularpentagon has 5 sides that are not all equal.
Not unless all angles are also equal. A rhombus is a parallelogram with all sides equal. A rectangle is a parallelogram with all angles equal. A square is a rhombus with all angles equal which is a parallelogram with all sides equal and all angles equal.
A rhombus has all sides equal and opposite sides parallel. This includes a square which is a special case of a rhombus with all angles equal (90 degrees) as well. If opposirte sides are equal but not all sides are equal, it is a parallelogram
No. The opposite sides are always equal to each other. All sides are equal only if it is a square or rhombus.
A triangle in which all sides are of equal length is an equilateral triangle.A triangle in which two sides are of equal length is an isoceles triangle.A triangle in which all sides are of different length is a scalene triangle.
3 equal sides = equilateral 2 equal sides = isosceles all sides different = scalene
All 4 sides are equal.
No, not necessarily. A parallelogram can have all sides equal, but still not be a square.
