Those parameters go into sim_db for EAP-SIM. Similar set of parameter
for EAP-AKA go to .milenage_db.

It's encrypted version of OP (which would be a random number).

Selected by whoever defined the parameters for AKA.

What components did you implement? If you are implementing EAP peer
method for EAP-SIM and EAP-AKA and in addition, the full SIM/USIM
operations for GSM and AKA authentication, then yes, you can use pretty
much any value as long as it matches with the client and server. If you
do not want to use Milenage for AKA, you could even replace hlr_auc_gw
in hostapd to provide some other parameters.
