It all depends on what type of Kickball you are playing. In traditional kickball you don't even have to touch the ball. As long as the ball touches the runner, the runner is out. Even if the "kicker" kicks the ball at a runner that is not on a base, the runner is out. There are different kinds of rules about this type of situation that can be adjusted to your liking
No it is not kickball.
any ball will do
In kickball, the ball is rolled down to home plate and you have to kick the ball. In softball, the ball is thrown underhand and you have to hit it with your bat. Sometimes in kickball, you can get pegged which is when they chuck the ball and you, in softball that's not allowed. Also in kickball, the ball is made of rubber, in softball its much harder and dangerous.
No, when a ball is hit on the ground, the runners must try and advance to the next base.
with your foot.
No. A sacrifice is when the batter turns around to bunt and lets everyone on the defense know what they are going to do. The batter is 'sacrificing' (allowing the defense to get him/her out) so the runners can advance one base.
If there were less than 2 outs and were runners on base, the runners go back to their bases and the batter is out.
