Changing players proportions depending on group rank?

I'm trying to make this script change the player's proportions depending on their group rank, the proportions part works correctly, but if there's no wait then the script doesn't fire correctly, the script doesn't fire after the player has died, and I want it to get every player it can.

game.Players.PlayerAdded:connect(function(Player)
    if Player:GetRankInGroup(4394297) <=2 then
	function playersize(player)
	local SizeVale = .87
	local humanoid = player.Character.Humanoid
	if humanoid then
		if humanoid:FindFirstChild("BodyHeightScale") then
			humanoid.BodyHeightScale.Value = SizeVale
		end
		if humanoid:FindFirstChild("BodyWidthScale") then
			humanoid.BodyWidthScale.Value = SizeVale
		end
		if humanoid:FindFirstChild("BodyDepthScale") then
			humanoid.BodyDepthScale.Value = SizeVale
		end
		if humanoid:FindFirstChild("HeadScale") then
			humanoid.HeadScale.Value = SizeVale
		end
	end
end
wait(3) --I want there to be no wait, but if there isn't then the script won't fire correctly
playersize(game.Players.CaptainAlien132)
--Can't figure out how to get every player
--I don't go back to proportions after I reset/die
else
    end
end)

First, your code is very messy, especially at the end. Your end and the else seem to be misplaced. Read this article on how to write cleaner code. I don't mean to insult you, but it's important to have clean code so that you and others can read it.

The reason the code doesn't execute when the character respawns is because you didn't code it to do so. There is an event called CharacterAdded which fires when the character is added. Whether it be first time, or respawning.

local function playersize(character) -- Localise your variables 
    -- Declare the function outside of the events. 
  
    for _, v in pairs(character.Humanoid:GetChildren()) do
        -- Instead of finding each individual value, use a loop.
        if v:IsA("NumberValue") then -- if it's a value...
            v.Value = ... -- set the number 
        end
    end
    print("Character added!", character) 
end

game.Players.PlayerAdded:Connect(function(player)
    client.CharacterAdded:Connect(playersize) -- Connect function 
end)

And finally, :connect is deprecated, use :Connect.
