Four is fairly simple (relatively speaking). Two in each hand. Not much more advice I can give you on that.
Five object juggling Find five soft objects, preferably either juggling balls or hackey sacks. You must have extreme patience for this, because odds are high that it will take you several months, maybe even a year or more, to learn this.
Start with just three. Do a three ball flash at the same height that you would juggle five balls. Just throw all three of them up, so they are all up there at the same time, then catch all of them. Do this several times, untill you can do it consistently.
Now, try a five ball flash. Each ball goes the same height, and lands in the hand opposite of the one it started in. The goal is to catch all five of them without dropping any. Yeah, right. The first time you try, no two will go withing a foot of he same height. One will land on your shoulder. One will land ten feet in front of you. The other three will be similarly scattered.
The way to overcome this obstacle is pretty much the same as with three balls: Throw them all, but don't make any attempt to catch them. Three should land close to eachother on one side, and two on the other. You want to be able to hear five distinct thumps, indicating that they have kept even spacing.
After this, there is really nothing you can do except do a five ball flash, then keep adding one additional throw each attempt untill you are eventually doing as many as you can. Good luck.
There is another method of juggling five which is much easier. It is difficult to describe, and you kind of have to see it. Basically, you start off by throwing one ball. When it hits it's peak, throw both balls in the other hand at the same time, but try to make them separate so that each lands in a different hand. When these two peak, throw do the same with the two in the other hand, and so on.
3 in One Hand
This one is difficult, but not particularly complicated. It's the same pattern as two in one, but higher and faster. To juggle six, just juggle 3 in each hand.
Seven
You learn in pretty much the same way you learn five.
More Than Seven You're on your own. I've qualified eight and flashed nine, but nothing beyond that.
