I've saved 4 pictures in 4 variables that means 4 pictures per variable. I'd like to subplot all those pictures (16 pictures) in a loop. Kindly, help me through this.

When you do your calling of subplot, you can enter your loop index as the third input.
for i = 1:something
...
subplot(4,4,i);
...
end

There are some small adjustments to be made for this to work. Also, I'm not sure what you want to plot your 'c' variables against, so you will need to change the 'x' values in the plot command with something else.
for i = 1:4;
h=fspecial('average', b(i));
c{i,1} = imfilter(a,h,'replicate'); % It's better to index variables rather than creating variables with numeric names. Matlab is much much easier to work with this way. Curly braces indicate cells
c{i,2} = imfilter(j,h,'replicate');
c{i,3} = imfilter(k,h,'replicate');
c{i,4} = imfilter(l,h,'replicate');
figure(i)
for j = 1:4; % NOTE: You CANNOT use 'j' for both the variable and the loop. Change one of them
subplot(1,4,j) % Creates a row of four plots per figure
plot(x,c{i,j});
end
end

What do you mean by 'showing an error'? Is there a specific error message, or are you indicating that you are having troubles producing the output you want. I'm assuming the latter, since your posted image looks like it isn't properly plotting the additional subplots. Did you properly index the sub plot command? Is it producing the correct number of figures?
