Hello all , I want to ask that, is there any way to plot two or more 3D volumes on same axis ? or say merging of two or more different 3D volumes on same axis having different graphical properties . like cube with sphere or cylinder with cube or cone with sphere etc.

Yes!
r = 0:0.05:0.5;
[xc,yc,zc] = cylinder(r);
[xs,yx,zs] = sphere;
figure(1)
surf(xc,yc,zc)
hold on
surf(xs*0.5,yx*0.5,zs*0.5+1.1)
hold off
grid on
axis equal

My pleasure.
They are intersecting here, to an extent. If you want the cone to be cutting through the sphere, do something like this:
figure(1)
surf(xc,yc,zc)
hold on
surf(xs*0.5,yx*0.5,zs*0.5+0.2)
hold off
grid on
axis equal
Note that here the sphere z-offset is 0.2 rather than 1.1 as in the original plot.
Experiment with them to get the result you want. Also, see the documentation for the sphere and cylinder functions.
