Performing Salaah in jamaat on the plane

Q: If one is travelling in a plane and wants to read salah with another brother in jamaat, in the limited space at the back of the plane would it be permissible due to space being limited:

  1. The imam stands directly in front of a single muqtadi?
  2. The imam stands almost next to muqtadi, just a few centimetres in front (due to space restrictions the ideal of one foot behind the imam cannot work)?
  3. The imam stands on the right of the muqtadi, muqtadi behind imam one foot length?

Performing five rakaats

Q: I prayed asr or Dhuhr I think, and I think in 2nd rak'ah I said ayah of al Faatihah wrong but was not sure so I ignored it and on the third rak'aat I noticed it was probably wrong so I took the 3rd rak'aat as 2nd and finished like normal and then did 2 sujood sahw. Any thing wrong with this?
