You may publish post(s) in any language you are capable of doing so, but keep in mind that it should look good in the end.
If it is not a massive "wall of text", use one post to publish your content. If it is a "wall of text one", most likely nobody will complain about multiple posts in different languages.
Hope i could answere your question?
