We were boarding our flight; already delayed because the inbound flight was late arriving. I was tracking our boarding progress. I saw 2 non revs waiting for seats and I sent a message to the gate agent to see if the airline non rev was going to get XX [seat]. The gate agent said that it was blocked 'but it was up to the  flight attendants.' I apologized for not knowing that it was blocked; but that it was ok with us. Then the other non rev boarded the plane. Her seat assignment was the aft flight attendant jump seat. I questioned her and she said that she was an airline flight attendant. I told her that we have had the aft FA jumpseat blocked for pandemic purposes and it's only for our airline employees and the FAA.There was a Ground Agent that was listening to our conversation and he used his radio to contact the boarding agent. She responded with 'The Captain said she could sit in the forward jump (flight deck).'I was pretty concerned that a flight attendant from another airline was given authorization by the boarding agent to sit in the flight deck. I questioned the Captain about this apparent new procedure and he said; 'NO'!After we; the flight crew; denied allowing the other airline flight attendant to sit in the flight deck; the gate agent then denied the first non rev to sit in XX.The boarding agent authorized and attempted to put a non-authorized person in the flight deck.
Flight Attendant reported issues relating to non-revs and where to seat them.
