Number of faces and edges and vertices of a decahedron?
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
What do you call a polyhedron with 10 triangular faces?
In general, any 10-sided polyhedron is called a decahedron. With 10 regular triangles for faces, you may have a pentagonal bipyramid.
Vertices of a decahedron?
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.

What is a octa-decahedron?
well judging by the previx octa and the sufix decahedra, i'd say that its a 3-dimensional irregular decahedron that's made up of octagons.
