A ladder is simply the rankings of tennis players. For instance on the laddder on my tennis team I am number 2, this means that there is only one person higher than me and plenty of people lower than me.
Usually 24 kids on one team.
2 players for singles and 4 players for doubles.
Single tennis matches differ from doubles only in that it is played with two people, one on each team. Where a doubles tennis match is played by four people, two on each team. The other difference is they may bounce the ball twice before hitting it rather than just once.
Well, if you are in school, try out for the tennis team.
