	local position = playerinstance
	for _, _player in ipairs(players:GetPlayers()) do
		local _position = _player.Position
		if _position.Value > position.Value then
			playerinstance = workspace:FindFirstChild("Player".._position.Value)
			_position.Value -= 1
		end
	end
end

players.PlayerAdded:Connect(onPlayerAdded)
players.PlayerRemoving:Connect(onPlayerRemoving)
#2 
position.Value = player.Name

your setting a value to a string, and thus the script is unable to compare a string value, so try this

local players = game:GetService("Players")
local function onPlayerAdded(player)
	local playerCount = #game.Players:GetPlayers()
	local playerinstance = workspace:FindFirstChild("Player"..playerCount)
	print(playerinstance)
	local position = playerinstance
	print(position)
	position.Value = playerCount -- changing the value to a number which allows the script to compare the two variables
	position.Parent = workspace
end

local function onPlayerRemoving(player)
	local playerCount = #game.Players:GetPlayers()
	local playerinstance = workspace:FindFirstChild("Player"..playerCount)	
	local position = playerinstance
	for _, _player in ipairs(players:GetPlayers()) do
		local _position = _player.Position
		if _position.Value > position.Value then
			playerinstance = workspace:FindFirstChild("Player".._position.Value)
			_position.Value -= 1
		end
	end
end
