The window on the right has one of their friends cut off from "a month later." One of their friends on the left is also missing from "2 years later" as well as the window in the far off future where one of their friends had become a mother. She is no longer there.
It's in the name- "Schoolmates". Presumably, they've transferred out or graduated, so they aren't schoolmates anymore... so they are absent from the later pictures. Not really ominous IMO. People move around, it'd be odder to me if everyone was still present... especially with the one where one girl has become a mother and the photo at bottom right which is labeled 25 years later.

Quite the opposite actually for japanese idealogy. The idea that a happy life would have you born and raised in the same city and even if you do move, you simply move to a bigger place within the same city and even if you and your friends go to different colleges, you can still hang out.
What this implies is that they aren't even friends anymore. Even if they don't work together or go to school together. Or worst case, someone died.
Quite a similar sad take happened in Lucky Star. The main group of Konota, Miyuki, Tsukasa and Kagami don't really hang out anymore despite being almost inseperable during the first 5 volumes. All conversations are held mostly via text messages, but Miyuki got it the worst as she was practically written out of the story for being "too boring and realistic".
