findpeaks gives you location of the peak as well
[pks,locs] = findpeaks(PeakSig,x);
dist = locs(2) - locs(1); %or whichever two peaks you want to know about

For different different graphs I am getting different different peaks. after counting no of peaks I want to find out distance between each of them means distance between first and second, between second and third and so on. How to do that ?

%If y is your signal
% you have to specify what is the major peak
% Major peaks and indices
[major_peaks, index]=find(peaks>=min_peak)
