Does the file have any of the watermarks supported by the watermark removal script? Which store is the file from?

In general, there's A) no single watermark / social DRM but rather dozens of different ones, and B), other than with hard DRM, it's difficult to even figure out if a book has a watermark. The plugin can only remove watermarks that follow one of the known schemes.

I don't know which watermarks are supported by watermark removal script, is there a list?

Which store is the file from?

From the Bookrepublic Store: https://www.bookrepublic.it/.

Anyway, in their privacy policy they say that the Social DRM they use is called Exlibris. They also have a link to their service: https://exlibris.bookrepublic.it/.
