There are 2 family raft rides (with big 3-4 person yellow rafts) and 2 two person tube slides. (One of those you have to enter the slow lazy river with a double tube, ride halfway around, get out and bring your tube up the stairs with you to slide back into the lazy river. I say this because if you don't make sure to grab a double tube when you enter the lazy river then you have to ride single tubes.)
There is also a racer slide section with 8 slides all right next to each other that you go down individually but you could be next to each other the entire time.
So that's 5 different slides plus 2 lazy rivers, 2 wave pools, and the huge kids splash playground you can do together.
