Is there any chance that this is an X-Y problem? That you do NOT actually need this to work after an "su", but instead, you just want the user to have the correct language when they login NORMALLY? If so, that is an entirely different question. If you simply want to configure each user's locale, so they each see the correct natural language when they login normally, see <https://wiki.debian.org/Locale> as a starting point. Be warned that some Desktop Environments override the locale variables that you try to set in dot files. If the users are using a fancy DE, you might have to configure their locale within said DE, using some sort of mouse-based clickery. http://xyproblem.info/
