When I was there I belive someone was their alone to get a seat for their party but to be seated your whole party has to be there or at least almost all of your party. I'm sure if they are like 5 minutes away they may or may not wait to seat your party but do not expect them to wait for everyone to show up
If you are only missing a person or two, it's possible, but you will likely be waiting a little while anyway so hopefully your party shows up by the time you are called, otherwise they might prioritize other parties.
Maybe, but i would NOT recommend it. Wait times will increase because of waiting, making it harder for them to get people in.
It depends how long it will take for your party to arrive. I assume they will be fine seat-ing you if it in the 10 minute range.
