I know maybe I need to use [iter] or [uzi] so that I can random 7 numbers at one time but I don't know how to random numbers I only need

It looks like you are trying to build some sort of quantized random note generator. In my work, I tend to have the random processes and the quantizing process be independent. I have a variety of things that generate random numbers in several flavors, and I have a couple flavors of quantizers, that conform the random processes to specific scales.

That said, as usual with Max, there are a number of ways to do what you want. A table would get you there quite easily:
