Ace Drummond aircraft?

[D.A.]

I'm building an aviation video library. My primary interest is WWI and Golden Age. There are a lot of little known movies and serials that may not have been cinema giants but have awesome footage of period aircraft. My latest find is "Ace Drummond - Amazing Exploits in the Air!!!" I had thought I was pretty good at identifying aircraft of that era until I saw this serial. There are 3 awesome looking biplanes that I can't identify. One is something along the lines of an Alexander Eagle Rock, but not quite, another looks like a New Standard D-25 with half the front cockpit covered over and the third is a double bay airplane with octagonal fuselage lines. All 3 are great looking airplanes. Can anyone ID them?
Thanks in advance.
