Thank you for your question!
I allow myself to merge your two recent questions, since they are connected.
If your appeal is rejected, you have the possibility to appeal the rejection decision with a lawyer (Berufung), or to file a Asylfolgeantrag at BAMF.
Please note however that both alternatives do not have much chance of success if you do not bring solid new evidence (if BAMF did not believe what you said during the interview), or, for the Asylfolgeantrag, if your situation did not change substantially since your first asylum claim.
To best study your possibilities, especially in order to see if you could try and stay on other grounds, I highly recommend you to contact a lawyer or a legal aid group. If you tell me where you live, I can help you with finding one!
All the best,
