A polygon has two types of measurements: side lengths and interior angles. The number of side lengths is equal to the number of sides the polygon has, while the number of interior angles is always equal to the number of sides. So, a polygon has two measurements: side lengths and interior angles.
All 4 sided shapes each equal to 360 degrees in angles
There are many shapes that have 12 sides. For example: A pyramid with a hendecagon (-sided) base; a decagonal prism; a hexagonal dipyramid; a dodecahedron, and many other shapes. Without information about what the shape is, and the lengths of its sides, it is impossible to even attempt to answer the question.
It only has two equal lengths out of however many sides like an isosceles triangle
Many different shapes; Square being the most obvious, Equilateral Triangle, Any Regular Polygon

An infinite number. A polygon with any number of sides can be equilateral (ie have sides of equal length).

A rhombus has 4 sides of equal lengths
Infinitely many. The smallest side of a triangle can have infinitely many possible lengths.
Four lengths indicate that the figure is a quadrilateral. Unfortunately, quadrilaterals are not rigid so that a set of four lengths can give rise to infinitely many shapes with infinitely many areas. This is on the same principle that a quadrilateral with four equal sides can be a square or a very thin rhombus.
A rhombus has 4 equal sides
None normally unless it is an isosceles trapezoid which has ends of equal lengths
3 or more sides of equal lengths
32-36 moer or less
(1 yard) and (36 inches) are exactly equal lengths.
None but it has end sides of equal lengths
