Like was said it depends on the CM that is working at the time. You usually only have to turn in one Quest paper per group (except Thrill Seekers w/ the stamp and all). Some CM's although make you fill out a Quest paper for each ticket or they may allow up to four(4) tickets per quest paper.
If they are Print at Home quests I would print off enough for one per person/ticket just in case there is a strict CM working
This may be confusing right now, which it was for me for my first time, but when I go there and inside VMK Central it was much easier and I understood what was going on
