A goal may be a scored directly from a goal keeper punt.
The goal keeper is always considered a defender, if he is in or out of the penalty area.
most of the time when a goal keeper takes the penalty shot but sometimes when the goal keeper of the other team is so much above his field or area the goal keeper may kick the ball from goal to the other goal.
If the goal keeper's team has substitutions remaining, then another goal keeper may replace them. If not, then a field player must be nominated to become the new goal keeper.
The laws do not prevent a goal from being scored from a goal keeper's throw.In practice no goal keeper can throw it that far, so there are no known examples.
The goalkeeper prevents the opposite team from scoring a goal.
No they can't there has to be a goal keeper, if a keeper gets sent off and their are no subs left to bring a keeper from the bench then one of the outfield players have to act as goal keeper instead

No. A goal keeper is allowed to dribble the ball, and this is not considered the same as "putting it down."
