This is a set of emission and miss fire codes, I feel that there is a random misfire on bank 2 that is the set of cylinders opposite #1 cylinder, one code is O2 sensor bank 2 #2 so that sensor is giving a bad signal and not necessary faulty in it self, start with checking plugs, leads, injectors and vacuum leaks on the bank opposite #1 cylinder bank, start here.
