At a glance only ApplicationName<LNG>= must not be correct snd functional.

ApplicationName<LNG>= there are 36 variations of the ApplicationName= key
Example: ApplicationNameAL=, ApplicationNameAR=, ApplicationNameBIA=, ApplicationNameCNS=, ApplicationNameCNT=, ApplicationNameCZ=, ApplicationNameDE=, etc

EDIT:
For the keys with boolean values (0/1), I particularly prefer a checkbox that is visually easier to understand. But either way it's good.

For the Lang= key it could be a checkbox group, one for each language and then when saving the INI it would form the key with the languages separated by a comma.
