If you replace n1 with n_{1} (and do the same for the other 5), you can use a loop.
Don't use numbered variables, use arrays instead.
Also, don't use clear all (use clear or clearvars to keep your workspace clean during debugging), and avoid close all if you don't plot anything.

That is not how MATLAB loop variables work. To know how to use for loops in MATLAB read the documentation:
https://www.mathworks.com/help/matlab/ref/for.html
Usually the simplest and most robust approach is to loop over indices.

To continue on what Stephen mentioned: you probably need something like the code below (and next time post code as code, not as an image).
for k=1:6
temp=n_{k};
%do something with temp
end
