I have excel file I want to plot the various column data against time column, then my question is how can I save the all graphs with different names at the same time?

I have attached Excel file. I want to plot seventh column (Time) with 8-33 columns. I have tried the following possibilities by using for as well as while loops but it plots the all graphs but can't save the single graph.

=by using for loop

[inFileName,inPathName] = ('*.xls','Select the xls-file');
a = xlsread(inFileName);
b = a(2:1394,:);
c = b(:,7);
for k = 16:33
    d = b(:,k);
    dd = smooth(d);
    a1 = plot(c,dd);
    xlabel('time (min)');
    ylabel('velocity (m/s)');
    title('Graph of velocity Vs Time');
    legend('zonal velocity m/s');
    print(sprintf('ImageFileName_%d',k),'.png');
end

=by using while loop

[inFileName,inPathName] = uigetfile('*.xls','Select the xls-file');
a = xlsread(inFileName);
b = a(2:1394,:);
c = b(:,7);
k=16;
while k<=33
    d = b(:,k);
    dd = smooth(d);
    a1 = plot(c,dd);
    xlabel('time (min)');
    ylabel('velocity (m/s)');
    title('Graph of velocity Vs Time');
    legend('zonal velocity m/s');
    print(sprintf('ImageFileName_%d.png',k));
    k=k+1;
end
