1)How can I get the 2 peaks from the picture below? Because these commands gives me the only the highest.
[gpeakG1,fpeakG1] = getPeakGain(G1);
gpeakG1_dB = 20*log10(gpeakG1);

I would use the bode function with three output arguments, then use findpeaks with the ‘mag’ and ‘wout’ arguments:
[mag,phase,wout] = bode(sys);
[pks,locs] = findpeaks(mag, wout);
Add the name-value pair arguments you need to get the result you want. The findpeaks function has considerable flexibility, but how much depends on your version of MATLAB, so be sure to read the relevant documentation for your version.

For #2, did you take a look at findpeaks()? (Requires the Signal Processing Toolbox.)
