Ughhhhh

Finally came back from dinner to finish the job and now the car is idling rough

Got a p0300 p0302 and p0308

I read that 1-4 cylinders is on the passenger side while 5-8 is on the driver side. Can soemone confirm please?

Also i didnt tighten the coil connection on the driver side second from the front coil on the first startup but cirrected that. Did i fry that coil? But from that earlier calxculation that should be p0306 i.e. Cylinder six
