Simply use a cell array with indexing:
Putting numbers into variable names is a sign that you are doing something wrong. In most cases using indexing is simpler, neater, and much more efficient.

[n,m]=size(img);
imgs = mat2cell(img,[n,n]/2,[m,m]/2)';
for ii = 1:4

k = 4;
[n,m]=size(img);
imgs = mat2cell(img, n/k*ones(1,k), m/k*ones(1,k))';
for ii = 1:k^2
subplot(k,k,ii);
imshow(imgs{ii});
end
