Accessgroups : Use D_pzAvailableAccessGroupsForAnOperator, Fetches the access groups for a given operator. If the operator name is not passed, uses the current operator.  

Accessroles: it is based on the access group, if the operator has more than one accessgroup, this will fetch Accessroles of all the accessgroups. You can customise D_pzAvailableAccessGroupsForAnOperator and added step to loop through valuelist pyUserRole and map to the results page, find the attachment for the same

FirstName: OperatorID.pyFirstName to display first name of the operator.

@G Pavan

Could you please provide more insights about your requirements? What's the intention to display Access Roles because it's more technical in nature? 

Thanks,
