From a quick glance, I know some of these.
I’ll aim for a couple for now as I’m about to go to bed, but there’s breadcrumbs for you to find more information about others:
07: Meiji 明治コーンスナック (Meiji Corn Snack) - 1997
38 & 39 (1997):
Apparently there are two lucky bags, one comes with a placemat, which is 39, the other with a mask. The blog linked is great by the way.
Originally the bag came with a tag on it.
