I'm not totally familiar with the offside rules but as far as I can tell, they apply when the ball is received and on none of those occasions could I see a player in the offside section. The ruling in the game should have been a goal.
Totally out of my realm, though: someone more familiar with football should chime in.

No, the offside rule applies from when the ball is played to the guy ruled offside (the second it leaves his team mates foot/chest/head).
Both blue shirted players are in an offside position when the ball is played towards them.
To be ONSIDE the dude receiving the ball would have to be level with or the other side of the GK (last defender in this play).
Correct decision. I’ve been a huge football fan my entire life.
If the GK was where he should be......in his goal then it would be ONSIDE.
this position is not offside. it has nothing to do with it from a distance. there is a ball coming from the opponent goalkeeper. there is an opposing player hovering around the goal post. Football is my life. I am doing this job professionally.
