I was sitting at [seat] XX. We are taxiing to takeoff; and there was no Flight Attendant sitting at XY!  I sat in my brace position wondering what happened to the other FA?  After it was safe to get up from our seats; the other FA walked up to work in first class. I asked where she was? She said she was sitting in the back; XZ.  I told her she is supposed to sit at XY; and she said okay.  On our descent to ZZZ; she sat at XY and I'm sitting at XX in my brace position. I looked towards my left and there is a passenger near me!  I told him to go back and sit down; but I could see we are seconds from touching down. I told him to buckle in the seat next to me.  He said he was feeling sick from the turbulence.  We arrive at our gate and disarm our doors and received the ALL CALL.  The Customer Service Agent knocked on the window waiting to get the thumbs up to open the door. But the FA cracked the door open at XY!!!  I told the FA she is not supposed to crack the door open; she pushed the handle down and the Agent was able to open the door. The CS Agent made eye contact with me and we both gave each other looks of shock.  All of the inflight crew were working the same plane back to ZZZ1. We all waited on the jet bridge as the airplane was cleaned.  I took the opportunity to discuss with the FA how nervous she made me feel. I wanted the other crew members to listen to the reasons as to why this FA made me nervous. I did not get any input from them.  I asked the FA if she went over the operations of [aircraft type] door. She said she had not flown [for over 5 months]; but she knew what she was doing.
Flight Attendant reported that another Flight Attendant who reportedly had not flown for over 5 months; sat in the wrong seat for takeoff and did not follow procedures for opening a door.
