Hello @Eri
Nice to hear from you again.
It's possible to apply for asylum again, it's called a "Folgeantrag". In order to be successful with such a second application you need to provide convincing evidence to prove that your personal situation respectively the situation in your home country changed for the worse since your first application. You have to show that there is new evidence that hasn't been known or taken into account during your first procedure.
Best regards,
Thorgen
