Welcome to the Wefugees Community and thank you for reaching out to us.
I assume you are currently holding an "Ausbildungsduldung", right?
In this case, you may apply for a residence permit according to section 19d of the German Residence Act which eventually will be issued for two years and subsequently can be extended (as long as the requirements are met). My colleague Éanna gave some information on this residence permit and its conditions here - you may also check "Handbook Germany" for further information (in various languages).
Dear @mbeon-Éanna, does Ahunwan have to secure the livelihood/cover the costs of the whole family in order to receive the 19d? Will the family members receive a residence permit as well or only the working person?
All the best,
