How would we move all players to multiple parts?

What about a table with vector3s and then use

Table[math.random(1,#Table)]

so you can put many positions and make the script do the job, I hope this can help you.

I can think of a couple solutions to your problem

Use positions which put the character above others

local position = Vector3.new(0,0,0)

for k,v in pairs(game.Players:GetChildren()) do
    if v.Character then
        v.Character:MoveTo(position) 
    end
end

Randomize them to teleport in the general area of the position

local cframe = CFrame.new(0,0,0)

for k,v in pairs(game.Players:GetChildren()) do
    if v.Character then
        local a = math.random(-10,10)
        local b = math.random(-10,10)
        v.Character.HumanoidRootPart.CFrame = cframe * CFrame.new(a,0,b)
    end
end

CFrame them higher and higher

local cframe = CFrame.new(0,0,0)

for k,v in pairs(game.Players:GetChildren()) do
    if v.Character then
        v.Character.HumanoidRootPart.CFrame = cframe * CFrame.new(0,k*5,0)
    end
end

I haven't tested these so I apologize as I am working on another project
