Photo help with 27 Yanks

[Lordstan]

Hello all,
I just picked up this lot of 18 snapshots.
The 70yo gentleman I bought them from told me his father told him they were taken in Spring Training 1927,
The first group include, what I think is a very rare snapshot of a team photo. While, I am not an expert on these, I have never seen a snap of a team before. Also the the pics below and to the left of the team supposedly show a young Lou Gehrig. It is hard to tell for sure, but does look a lot like him. To the further left are 4 pictures containing Herb Pennock, two in action. The last of the first group is labeled Chapman.
In the third picture upper left, is Tony Lazzeri.
The rest I am unsure of. This is where I would like some help from the board to identify some of the other players.
I will post close ups of faces if anyone would like.







Thanks in advance for any assistance.
Mark

Edit:Sorry the pictures came out a lot smaller than I thought. I will rescan them tomorrow a bit bigger
