Most doors in pressurised areas on todays airliners are "plug-type" doors. That means the opening area is smaller than the door area. When the door is closed it is held in position by door stops and lock bolts. The higher pressure inside the cabin presses the doors in their frame. A rubber seal is used to prevent leakage. Door open/close and locking mechanism vary from type to type. Doors an big aircrafts are very heavy. But I don´t know an exact weight.
Hope my answer gives you a rough idea. I know it was held very general. If you have more specific questions, please let me know. I´m sure some people here will be able to answer, too.

Your question is a little too general to give a decent answer. The A320 pax door lifts up to clear door stops, then swings out on a support arm. The 767 lifts up into the ceiling area. Lots of variation, no simple answer. What sort of info are you looking for?
The primary function of the design engineer is to make things difficult for the manufacturer and impossible for the AME.

Some (okay, all) of the weights quoted seem... odd. Miamiair, are you sure about all these? Surely the 757 L1 door doesn't weigh two and a half times that of a 737's? (And surely it's taller than 5'5" )
