So, I have Configured between them now some errors are coming after running ./run.sh in free5gc like:

and in Amarisoft Web GUI
PLMN was different for Free5gc but I modified the PLMN to 00101 which was provided by Amarisoft. In gnb PLMN is already pre-configured.
I’m confused regarding TAI, TAI is pre-defined as tac: 000001 # Tracking Area Code (3 bytes hex string, range: 000000~FFFFFF)
