Dear Student,

The solids that have 
(i) 4 faces - Triangular pyramid (base is a triangle)
(ii) 5 faces - Rectangular pyramid (base is a rectangle)
(iii) 6 faces - Cube
(iv) 1 surface - Sphere
(v) 4 vertices - Triangular pyramid 
(vi) 5​​​​​ vertices - Rectangular pyramid
(vii) 6 vertices - Triangular prism
(viii) No vertices - sphere
(ix) 9 edges - Triangular prism
(x) 2 edges - Cylinder
(xi) 1 edge - cone
(xii) No edges - sphere
(xiii) 5 faces and 5 vertices - Rectangular pyramid
