The picture of the dual Spitfire -- you have managed to catch a very rare beast above it, she
looks like a Jackaroo to me, a rather special passenger carrying version of a Tiger Moth. I have only seen one before at an aircraft Rally back in the 60's.
Not according to my brother who is a major aviation buff, he says: "Blackburn B-2 I would think (no sweepback to the wings, but otherwise superficially similar to a Tiger; seating was side-by-side). Importantly, there's one (the only one I believe) based at nearby Old Warden".

A quick google search for the registration revealed that it is, indeed, a 1936 Blackburn B.2 Series 1 C/N 6300/8. a very rate rare beastie, to say the least. It is owned by the Shuttleworth Collection, so in good hands.
