If you mean the regular polyhedra, they are:
tetrahedron, cube (or hexahedron), octahedron, dodecahedron, icosahedron, (Plato's 50) plus: small stellated dodecahedron, great stellated dodecahedron, great dodecahedron, great icosahedron for 9. Maybe a sphere is a perfect curved 3D figure.
The special features of 3D shapes are they all are 3D which means they are fat but 2D shapes are flat they can not stand up.

3D shapes have three dimensions, namely length, breadth and height.
Polygons are 2d shapes whereas polyhedrons are 3d shapes
No because 2d shapes are plane such as polygons but example of 3d shapes are: pyramid, cone, cuboid, cylinder, sphere ... etc
3D shapes have edges, sides, and intersecting points

3d shapes with six faces are called hexahedra.
Cubes, pyramids, cones, and spheres are all 3D shapes.
Polygons are 2d shapes whereas polyhedrons are 3d shapes

Give vidoes to understand the 2d and 3d shapes clearly

2D shapes are flat and have only two dimensions—length and width—while 3D shapes include depth, adding a third dimension. This allows 3D shapes to occupy physical space, whereas 2D shapes are confined to a plane. Additionally, 3D shapes can have volume and surface area, whereas 2D shapes are characterized by perimeter and area. Examples include squares and circles for 2D shapes, and cubes and spheres for 3D shapes.
There are infinitely many 3d shapes and many of them do not have specific names.
2d shapes only have length and width, while 3d shapes have length, width and depth.
