I came up with names for dozenal numbers in multiple languages.
Take note, I only know English, so I have to do my best with with the only tool I have: Google Translate, and then I will talk to people who know the language. I only consulted about Hungarian so far, so English and Hungarian are the only systems that are final.
I try to do some universal scheme with zen, duna, and trin, and it will sound somewhat similar to the current schemes for each language.

French
French counts weird.
For numbers above sixty, they so something like:
70: Sixty ten
80: Four twenties
90: Four twenties ten
I could have done sevenzen as "sixzen zen", but I just completely eliminated that clause, and made it like every other language.

German
For zen, I kept it "dutzend", instead of shortening it because
* 10 is "zehn", and "zend" would sound similar
* "zehn" is also like "teen" in English (so i did "zend" as "zeene"), but German does either "zig" or "ßig" for "ty", and I could not find a suitable alternative except "dutz". (I really can't do suffixes that are proper German words because of how German combines words)
