Dear @LuckyD,
Thank you for sharing your question with the Wefugee Community!
Could applying for a residence permit according to section 25b of the German Residence Act be an option for your friend? You may want to check the requirements and details here.
If people reside in Germany already either 8 or 6 years (if living with a minor/unmarried child as a family unit for at least 6 years without interruption) with a "Duldung" or "Aufenthaltsgestattung" and are able to proof "lasting integration" into the German society (work, speaking the language etc.), applying for this one could be worth a try.
However, I would also recommend your friend to seek personal legal advice, i.e. in a counselling centre. Please let us know if you need support in finding one in your/your friend's home town.
All the best,
Meike
