It definitely is possible – and the plugin already ships with translations for many different languages. Here for instance is a screenshot of some meta walker output with WordPress configured to use German (de_DE):

The above links were really just to give you some insight into using the meta walker since you expressed an interest in knowing which files it was comprised of – but it’s important to note it doesn’t really have any templates of its own that you can safely override and customize as you might do, for instance, with the single events template.
Ordinarily, the best way to translate things is by working with tools like POEdit: though geared more to WordPress as a whole, there is a good explanation of the basics over here.
Does that help?
