What is the 3d name for octagon
It's a 2D shape.
there isn't another name for an octagon. It is simply known as an OCTAGON

A 3d shape with 10 sides is called a decahedron. I have added a link with some pictures of them. As you can see they look very different but all have 10 sides or faces.

No, it is not.
A 3D octagon shape is called an "octagonal prism." This geometric figure consists of two parallel octagonal bases connected by rectangular lateral faces. The octagonal prism retains the properties of an octagon in its bases while extending into the third dimension.
It's a 2D shape.
Octagon. * * * * * An octagon is 2-dimensional. The regular 3-d shape (all faces the same) is the octahedron, but a hexagonal prism also has 8 faces.

An "octagon" is a real name!
if its 2D its a octagon, if its 3D its a octagonal prisim
The question is ambiguous. An octagon is a 2-dimensional shape with 8 edges and 8 vertices. Does a 3-D octagonal shape mean one with 8 edges or 8 faces or vertices, or faces which are 2d octagons?
