I want to create a plot with the handle 32. Is there any way to do that?

As others have mentioned, the answer is no. But, can I ask why you would want to do that?

If you explain why you would want to do this, we could possibly suggest an alternative approach.

No. But you can specify a "tag" of "32", and then use that to refer to the object using FINDOBJ.
For example:
hold all;
h1 = plot(rand(1,5))
h2 = plot([1 -1 -1 1 -1])
AAA = findobj('tag','32')
set(AAA, 'linewidth',20)

What is meant by a "plot" in this case? You can create a figure with the number 32 just by using figure(32) but you cannot control the exact numbers of any lower level graphics object.

I doubt it. If you could create one plot with handle 32, you could create another, and then it wouldn't be unique any more. This could lead to some serious bugs.
MATLAB seems to choose very particular values for handles. On my machine, the first plot of a session is 174.00xx for some value of xx (this seems to vary). Then each new handle is incremented by 0.0006.
