no you can not cut an ice hockey stick, but you can break it with the right amount of force you can if you get a big scissors

You shove a plug in it
Composite
No
It really doesn't make a difference (except that wood sticks tend to be heavier and you also get more flex in a composite stick). It is mostly your preference.

A composite hockey stick is made from a synthetic material such as carbon fiber and is seen as lighter and to have more flex than a wood hockey stick. The flex of the stick is often rated on the stick and the amount of flex is a preference of the player. Flex can be seen as important because it causes a snapping of the stick during a snap or slap shot which causes the puck to release at a higher velocity. however often the more flex a stick may have the easier it may break.

The plastic film around the stick around 5cm up from the hook
Whichever one you feel more comfortable with.
Depends on where the cut is but cutting it to fit your height is fine.
