I was B position; while checking cabin I see a passenger seated in X6 next to the D Jump Seat which was [NAME]. I asked A FA and D FA what's up?  D FA I believe [was] not aware of the rules to social distance us [by] blocking X4 and X5. D FA thought it was OK to offer that seat to a non- rev.  I was not A so again repeated it is not OK; yet we were now pushing back. Later in flight I found out the agent was not the one to request from us but D FA offered it up so they assigned a non rev to X6 . We had many open seats in main cabin. A FA; understanding where I was coming from and he too being here much longer than the two reserves understands we have rules we have a contract it is not up for debate . This is our jump seat. A FA informed us as a whole that he would report this situation and I thanked him and agreed. I want us all to learn from this. As I don't think either of them still understand and shouldn't put another crew or agent in jeopardy of getting in trouble. If I am incorrect and she was in the right and can continue going above and beyond accommodating passenger next to her jump seat in X6 for future flights then please reply. If I am correct; could you please address this to the entire flight attendant group for clarification.
Flight Attendant reported confusion whether a non-rev passenger could sit in a specific jump seat.
