Are you running hlr_auc_gw process at all? If yes, with what command

Those are configured to hlr_auc_gw, not hostapd.

The parameters you specified are for EAP-SIM and they are configured in
GSM triplet file (-g command line argument for hlr_auc_gw). Milenage
parameters (IMSI, Ki, OPc, AMF, SQN) for EAP-AKA would be configured in
the Milenage file (-m command line argument for hlr_auc_gw).

OPc is an encrypted operator variant algorithm configuration field. You
would need to get that from the USIM manufacturer (or to be more
specific, as an operator you would likely specify your own at some point

No, you will need to use matching values with the USIM.
