plot the first, specifying a color. Use "hold on". Plot the second, specifying a different color. Plot the third, specifying a third color. Continue for the result of your populations. At the end, "hold off".

Many thanks for your help, but how can I specifie the color in ksdensity function please? Because I tried to do that and I got an error.

Do not rely on ksdensity() to plot the values. Plot them yourself like is shown in the first example at http://www.mathworks.com/help/stats/ksdensity.html
For information about hold() see http://www.mathworks.com/help/matlab/ref/hold.html
