He is ejected and may be fined or suspended, but the game he is ejected from he can not return to that game
Yes, that's essentially what being "ejected" means.
After being ejected, a player may receive a technical if they refuse to leave or continue to harangue the officials or players.
In high school, the ruling is that any player that leaves the bench to participate in a fight, whether it is to help or harm, the player is to be ejected.
When a player is shown a red card he being sent off (ejected from the match). This player must sit out the rest of this match. In addition, this player cannot stay in the field environment and must leave the area.Most leagues also prohibit this player from playing in the next match as well. Sometimes more than one.
No. The goalie only has to leave the field if he/she is given a red card, same as any other player.
Yes, but only in a very specialized instance. Only when a double technical is called and it is the second technical foul for one of the offenders. In this case, the player with the second technical foul is ejected and both teams will shoot free throws, which is not normally the case with double technical fouls. The team without an ejected player may choose their own shooter, however, the other team can select any player on the opposing team to shoot in the place of the ejected player. This is effectively the only time a player will come off the bench to shoot free throws. The only other instance this is a possibility is when a player is injured and must leave the floor prior to technical free throws being taken.
FIFA law now states that players ejected before the beginning of the game must leave the field and take no part in the game, but can be replaced. This is a notable difference with regard to ejections after the start of the game, wherein players ejected cannot be replaced. The event should be reported to the league. Yellow cards can also be issued before the start of the game.

Under the FIFA Laws of the Game, there is no requirement for a cautioned player to leave the field.
No, I don't think so.
Providing the player is at no time offside, then yes.
No. Once this extra player is discovered, he/she will be cautioned (for entering the field of play without the referee's permission) and required to leave the field. Any goals scored during this time could result in the match result being invalidated and, possibly, the match replayed.
