for i=1:100
load (['a' num2str(i) '.mat'])
hold on
end

figure(1)
for i=1:100
load (['a' num2str(i) '.mat'])
plot(a)
hold on
end
hold off
However the problem is the color: you can try to build a 100x3 matrix containing the values of the colors you want but it is too long plus for a 100 plots you might get colors that are too similar

You can try
plot(eval(['a' num2str(i) '.mat']));
It is said that eval may give the wrong result sometimes, but it have not happened for me yet. However, if you want to do something else that is more safe you can do
q = load (['a' num2str(i) '.mat'])
qnames = fieldnames(q);
plot(q.(qnames{1}));
or you can search for a replacement for eval.
