A 3 dimensional figure
It is not clear whether the question means the shape has ten faces of which 4 are square and 6 are not, or 6 faces of which 4 are square. In the first case the shape would be a 16-hedron. The second is impossible.
Xeptagon
Assuming it has 16 triangular sides plus a base making 17 faces in all, it would be a heptadecahedron. If it is a 16-faced shape then a hexadecahedron.Assuming it has 16 triangular sides plus a base making 17 faces in all, it would be a heptadecahedron.

An octagonal prism.
A tetrahedral prism is a three-dimensional geometric shape that has two congruent triangular bases and four congruent lateral faces that are in the shape of triangles. The lateral faces connect the corresponding vertices of the two triangular bases, forming a solid with six faces, eight edges, and four vertices.
Nonahedron
An octagonal prism, possibly.
Two cubes have 12 faces, 24 edges, and 16 vertices.
