Dear Al Amin,
Thank you for reaching out to the Wefugees community.
With the residence permit "soggiornante di lungo periode - CE" from Italy you can get a resident permit in Germany according to § 38 a Residence Act (Aufenthaltsgesetz). You need also your own income and the health insurance in Germany.
