How difference between these three windows?
If Iam have signal(row vectrors) with length(32) ,How applied this three windows on my signal ?

Assume x is your signal
x = randn(32,1);
x = x.*hamming(length(x));
The differences in the windows are largely about the width of the main lobe differences in the level of the sidelobes. You can launch wvtool to compare the sidelobe behavior.
wvtool(hamming(32))
Note that some important measurements about the window are displayed at the bottom.

Yes, after you window the data, you can obtain the DFT of the signals and then take the modulus squared for the magnitude-squared DFT
w111 =hanning(32) ;
Sig = Sig.*repmat(w111,1,8);
SigDFT = abs(fft(Sig).^2);
