A decahedron is a polyhedron with 10 faces. There are several versions of a decahedron, but none of these are regular. By definition, they all have 10 faces. There is the octagonal prism - with 24 edges and 16 vertices, the square anti-prism, with 16 edges and 8 vertices, the square cupola, with 20 edges and 12 vertices, the pentagonal bi-pyramid, with 15 edges and 7 vertices and the augmented pentagonal prism, with 19 edges and 11 vertices. See, for example, http://en.wikipedia.org/wiki/Decahedron
In general, any 10-sided polyhedron is called a decahedron. With 10 regular triangles for faces, you may have a pentagonal bipyramid.
A decahedron is a closed 3-D shape with ten polygonal faces. There are 32,300 topologically different decahdra and, since none of these are regular, the term is ambiguous. Some simple decahedra are:nonagon-based pyramidoctagon-based prismsquare antiprismpentagonal dipyramid.The number of vertices will depend on which of these - or the other 32,296 decahedra - you have in mind.

No.
It is not a regular polyhedron because it has unequal sides
In geometry, a decahedron is a polyhedron with ten faces. There are 32300 topologically distinct decahedra and none are regular, so this name is ambiguous.One regular decahedron is an octagonal prism. Along with its 10 faces, it has 16 vertices and 24 edges.

The formula for the volume of a decahedron will depend on which one of the 32,300 decahedra it is, and in many cases it is likely to be quite a complicated formula.

think of a square but instead of 4 surfaces, 10 this is the decahedron
No. Decahedron is a 3-D shape with ten faces.
A decahedron is a solid shape with ten flat faces.
