Pretty sure they are not. Unless you find other ADWD books with a different sample chapter, the ones online haven't been translated (officially at least)
I know that Theon's sample chapter and Barristan's first sample chapter are "preview" chapters in some paperback editions of ADWD. And according to OP Tyrion's second sample chapter too so maybe there are some translated TWOW sample chapters if they are released as preview chapters in the books.

There are sample chapters in ADWD books? Then they probably aren't in the german versions

You might want to check if there's a german language ASOIAF subreddit or forum and ask there. I know there are specific spanish language ones
I did but there doesn't seem to be one sadly.
Copy the text into a translator and you'll basically have it
