I know some, I guess, hope I do not butcher them:

German(native): Bitte/ Danke (sehr) or Vielen Dank,

English: please/ thank you (very much),

Japanese: どうぞ or おねがいします or ください/ (どうも)ありがとう(ございます) (Which is douzo (when you offer someone something, I think, onegaishimasu/kudasai (if you want something or someone to do something, which is following the request.)/ (domo)arigatou(gozaimasu),

Norwegian: vær så snill / (tusen) takk,
(Which is like “Sei so gut/lieb”/ “Tausend Dank” in German.),

Romanian: vă rog or te rog (formal/informal)/ mulțumesc ((foarte) mult) or mersi (mult) (ă is a short a, I guess and ț is like the ts from “its”, or a German z)

French: s’il vous plait (that one I had to look up on how to write)/ merci

Polish: proszę (bardzo)/ dzięki or dziękuję (bardzo) (Like proshe/ djenki/djenkuje)(ę is nasalized)

Portuguese: faz favor or por favor/ obrigado or obrigada (male/female) (o is spoken like an u) (I do not know much Portuguese (like French and Polish), in my book (European Portuguese faz favor and por favor are used, but I do not know the differences.)

I get this question quite often, but to be frank, I just like the sound of it.

Oh, just like in Japanese, did not know that, they have the ten thousands quirk too. Would love to learn more Chinese and other languages, but I lack free time.

I can count to ten in more language than I am able to speak (I just love learning stuff):

Can count above ten:
German (native), English, Norwegian, Romanian, Russian, Japanese

Can count only up to ten:
French, Polish, Mandarin

I am learning Romanian at the moment, those are 0-10: zero,
unu/ una,
doi/ două,
trei,
patru,
cinci,
șase,
șapte,
opt,
nouă,
zece
