Exhaust manifold to pipe question

I have the 2.4l motor, one of the studs has come out of the exhaust manifold where the pipe connects to it, and the pipe has moved a little, it looks like there are 2 gaskets. Are they both the same? Can someone tell me what gaskets to order and aso the stud and nut?

 

Thank you this helps these look like the studs I need but the gaskets I want are the ones that go between the pipe and the flange on the manifold, I think I found them but it's confusing because there are 2 gaskets side by side and I don't know if I buy 2 of the same or if they are different. They are both round.
