-hedra.
There are infinitely many 3-D shapes so it is not possible to name them individually.
Polygonal (2-d) shapes get their (not there) names from the number of sides; polyhedra (3-d) shapes get their names from the number of faces.The names of other shapes: circles, ellipses, torus, cardioid etc have different origins.
3-d shapes are not made from 2-d shapes. 3-d shapes may have projections onto a plane that are 2-d.
3 dimensional shapes have breadth, width and depth whereas 2 dimensional shapes have only breadth and width

There are many 3-D shapes (including ones that don't have names). Here are the commonly known 3-D shapes in general: -hemisphere -cube -cuboid -tetrahedron -cylinder -octahedron -cone -prism -sphere -pyramid -dodecahedron
3 dimensional shapes have breadth, width and depth whereas 2 dimensional shapes have only breadth and width
Polyhedrons
Triangular based pyramid with no bottom. That is, if you meant 3-D shapes, presumably?
Triangle, square, and pentagon
Yes, there are 4-D shapes, also known as four-dimensional polytopes or "polychora." Just as 3-D shapes are defined in three spatial dimensions, 4-D shapes extend this concept into a fourth dimension. While we cannot directly visualize four dimensions, we can represent 4-D shapes mathematically or through projections into 3-D space, similar to how a 3-D object casts a 2-D shadow. Examples include the hypercube (or tesseract) and the 24-cell.
circles and ovals In 3-D, spheres and oblate spheroids
No because isosceles triangles are 2 dimensional shapes.
