Thanks guys! I think you nailed both of those IDs.
Ol' Boob made appearances with the Reds in 1923, 1924, and 1925. His Baseball Reference page doesn't show this, but his SABR bio says that he played with the Knoxville Pioneers of the Appalachian League in 1922 before joining the Reds:

Pete Donohue played for the Reds from 1921 - 1929, so that gives us Fowler's 3 years on the team as the options.
That leaves the guy in the middle of the photo of the three Reds. It's late so I only did a little bit of looking, but nobody jumped out right away.
