names=4;   
for i = 1:names
            totalnames = filename{indx};
end

where filename is a cell array of a list of 4 file names and indx is the location of the files that the user selected from the list dialog box. I am trying to store the names of the files that the user chose through the for loop into a matrix. Can someone please help me out with this?

Unless you can guarantee that all file names have the exact same length, you need to use something other than a char matrix. Either a cell array, or a string array:

names=4;   
totalnames = cell(1,names);
for i = 1:names
   totalnames{i} = filename{indx};
end

I am getting the same name in all the cells in the totalnames array, would you know any solution to that?

That's because you're using the same indx on each loop iteration. The indx value doesn't change in this for-loop. If indx is a vector, you don't need a loop (try out my answer). If indx is not a vector, you should tell us more about that variable.
