The large twin engine biplane is almost certainly J6856 the Vickers Virginia Mk I prototype possibly serving with 9 Sqn (I have a very similar photo in another Putnam book), but I doubt it went into service with the 'fighting tops'. The rather soggy transport type looks like a Vickers Victoria, the single engine biplane is a DH9a, which came in more varients than a well known brand of beans. As for the crashed aircraft I went round in circles until I realised it was a rear 3/4 view of another Vickers Virginia, this time a Mk IX or X, (probably the latter as the structure appears to be metal and to have survived a fire) which had a prominent tail gunners position instead of the 'fighting tops' of the prototype.
BTW, for those who haven't looked at the link I really think you should, and who doesn't think those seaplanes look the biz?
