A regular expression to match the seconds is trivial: m\d+s.

The problem is that a regular expression works on a single string. There is no way for a pure regex solution to group the files by the start of the name and then apply a sequential number, because the regex only sees one filename at a time, and doesn't maintain any state between invocations.

If you want to do this in code, it should be fairly easy, but you'd need to specify which language you were using.

If you want to use a renamer tool, you'll need to consult the documentation to see if it can do this sort of thing, and if so, how.
