Why don't the axes handles work ? I have R2013a, and the docs say you get a handle from polar, and can pass this as the first parameter
K>> h = polar (t(1:5),r(1:5), '-*')
h =
1.8470e+03
K>> polar (h,t(6:end),r(6:end), '-O') Error using polar (line 23) Too many input arguments.

The HOLD command should work:
t = 0:.01:2*pi;
polar(t,cos(2*t).*cos(2*t),'--k')
hold on
polar(t,sin(2*t).*cos(2*t),'--r')

Probably the easiest way is to plot each of the diagrams on its own axes, and then use copyobj() to copy them on to one common axes.
polar() is implemented as creating a circular patch() object to hold the diagram, drawing in the spokes and discs, using text() to add labels, and using pol2cart() to convert the polar coordinates to cartesian coordinates for the purpose of drawing the graph itself.
polar() detects that presence of the patch() object and will not draw it again if it is present there. This is why you need to draw on different axes in order to be able to end up with multiple diagrams.
After you copyobj() you will need to offset all of the coordinates of all of the graphics objects so that they do not overlap. This will be a bit tricky as text() objects will only accept data coordinates, not pixel coordinates.
Also note that polar() creates two axes.
I would suggest that you might want to consider using subplot() instead of having multiple diagrams on the same graph.
