Avoid hiding an index in the name of the variables. Then the solution is easy:
a = cell(1, 3);
a{1} = magic(2);
a{2} = magic(3);
a{3} = magic(4);
for ia = 1:numel(a)
save(sprintf('File%d.mat'm ia), a{ia});
end

You could do something like this using the dlmwrite function:
for i=1:1:50
dlmwrite(sprintf('%d.txt', i), magic(i));
end
This will save the first 50 magic matrices to text files named 1.txt, 2.txt, 3.txt, etc.
