One of the tunes with the red notes in the right hand is Clementi Sonatina . Unfortunately I don't remember where I got it and there is nothing on the score to remind me.I'm running out of puns now to keep up!
If it's one of my scores it means repeater rows (4/5). I'm only a recent accordionist so I find a bit of fingering helpful. I'm also a cheapskate so my free music programme doesn't do circled fingering, but it does do colours!
