I'd call ten in one block alone 'lots', but just for you, I'll get an accurate figure at the next SAG meeting.
No, no, please don't trouble yourself. I didn't see anyone celebrate in E or S, although I saw 3 or 4 spotty teens get escorted in the Away corner late in the game. I also saw a few jump up in corporates (not unusual). Couldn't see any jump up in N stand. I'd call 'lots' what we will see in the Man U SF second leg, and by lots I mean well unto 3 figures and all over the ground, as they will get tix easily from the ground. And none will be ejected.
