And the other question is... how do you like target everyone around a unit and make the equal to place [array] but with different numbers on the array?

Add every unit around you to a unit group.
Set integer: Number of units in that unit group.
For each integer between 1 and integer:
Pick random unit from unit group
Remove unit from unit group
