old_file_names = { ...
'1_ss_ddd_080_y000.txt', ...
'1_ss_ddd_080_y001.txt', ...
'1_ss_ddd_080_y002.txt'};
new_file_names = strrep(old_file_names,'080','020');
for ii = 1:numel(old_file_names)
movefile(old_file_names{ii},new_file_names{ii});
end

The loop works the same whether there are 3 or 100 or 100000 files.
However, one thing to consider is whether MATLAB's working directory is the directory where the files are. Because if not, you ned to refer to the files by their full paths. This renames all the .txt files in the directory your_directory:
your_directory = 'C:\path\to\some\folder';
s = dir(fullfile(your_directory,'*.txt'));
old_file_names = fullfile(your_directory,{s.name});
new_file_names = fullfile(your_directory,strrep({s.name},'080','020'));
for ii = 1:numel(old_file_names)
movefile(old_file_names{ii},new_file_names{ii});
end

I guess one of the files didn't have '080' in the name (possibly because it was already renamed by a previous run of this code).
To handle that situation, I skip the file in that case:
your_directory = 'C:\path\to\some\folder';
s = dir(fullfile(your_directory,'*.txt'));
old_file_names = fullfile(your_directory,{s.name});
new_file_names = fullfile(your_directory,strrep({s.name},'080','020'));
for ii = 1:numel(old_file_names)
if strcmp(old_file_names{ii},new_file_names{ii})
continue
end
movefile(old_file_names{ii},new_file_names{ii});
end
