I tried using 'hold on' and 'hold off' but don't know where to place it.

samplingfrequencies = [5, 7, 8, 9, 20];
colors = 'bgrcm';
i = 1;
for n = samplingFrequencies
    t = 0 : (1 / n) : 5; 
    y = sin(8 * t * (2 * pi));
    subplot(5,1,i);
    h = plot(t,y,colors(i));
    set(h,'marker','*')
    axis([0, 5, -1, 1]);
    title([num2str(n), 'Hz Sample Rate']);
    xlabel('time');
    ylabel('amplitude');
    i = i+1;  
end

Something like this maybe?

samplingfrequencies = [5, 7, 8, 9, 20];
colors = 'bgrcm';
i = 1;
for n = samplingFrequencies
    t = 0 : (1 / n) : 5; 
    y = sin(8 * t * (2 * pi));
    subplot(5,1,i);
    hold on
    h = plot(t,y,colors(i));
    set(h,'marker','*')
    axis([0, 5, -1, 1]);
    title([num2str(n), 'Hz Sample Rate']);
    xlabel('time');
    ylabel('amplitude');
    i = i+1;  
end
hold off
