5 Shapes, 8 sides
2 shapes
A shape with four sides and four vertices is called a quadrilateral. Common examples of quadrilaterals include squares, rectangles, parallelograms, and trapezoids. Each of these shapes has four sides of varying lengths and angles, but they all share the characteristic of having four vertices.
It can form two quadrangles and three triangles. It has seven sides.
A cube has 8 corners (or vertices). Similarly, a cuboid also has 8 corners. Both shapes share this property due to their three-dimensional rectangular structure.
2 faces can't share the same face, and they cannot share ALL vertices and edges either

A 3-sided polygon is a triangle. There is no diagonal for that shape since all non-adjacent vertices share a line segment!
When two faces of a polyhedron share a side, they form an edge. This edge is a line segment where the two faces meet. Each edge connects two vertices and contributes to the overall structure of the polyhedron. The arrangement of these edges, along with the faces and vertices, defines the shape of the polyhedron.
There are different formulae for different shapes. And since you have not bothered to share any information about the shape, I cannot provide a more useful answer.
The flag of Nepal is the only national flag that is not rectangular in shape. It consists of two stacked triangular shapes.
they are fluid
The shapes would be around 9 and 8 sides in total.
The trick to making shapes with a certain number of lines is to allow the shapes to share lines between each other. You also have to make sure that you aren't letting them share too many lines; in fact, to get thirteen lines for squares, you'll need to share three lines (technically called segments in mathematics). One way to do this is to simply draw a rectangle and sketch three lines between it.
