How to control all objects that have the same name?

i need help with a script where i need it to get all the objects by the name of "Notification" with the exception for the very bottom one and subtract 55 from their y axis.

---------[Constants]-------------------------------------------------------------------------------

local X = -200
local XCLOSE = 200
local Y = 355
local YCLOSE = 355
local YMINUS = 0
local Queue = 0

---------[End]-------------------------------------------------------------------------------------

function Notify()
	if Queue == 0 then
		local Notification = script.Parent.NotificationORIGINAL:clone()
		Notification.Name = "Notification"
		Notification.Parent = script.Parent
		Notification:TweenPosition(UDim2.new(1, X, 0, Y), "Out", "Bounce", .5, true)
		Queue = Queue + 1
		wait(5)
		Notification:TweenPosition(UDim2.new(1, XCLOSE, 0, YCLOSE), "Out", "Bounce", .5, true)
		wait(1)
		Notification:Destroy()
		Queue = Queue - 1
	else
		YMINUS = 55 * Queue
		script.Parent.Notification:TweenPosition(UDim2.new(1, X, 0, Y-YMINUS), "Out", "Back", .5, true)
		YCLOSE = YCLOSE-YMINUS
		local Notification = script.Parent.NotificationORIGINAL:clone()
		Notification.Name = "Notification"
		Notification.Parent = script.Parent
		Notification:TweenPosition(UDim2.new(1, X, 0, Y), "Out", "Bounce", .5, true)
		Queue = Queue + 1
		wait(5)
		Notification:TweenPosition(UDim2.new(1, XCLOSE, 0, Y), "Out", "Bounce", .5, true)
		wait(1)
		Queue = Queue - 1
		Notification:Destroy()
	end
end

game.workspace.PlayerJoined.OnClientEvent:connect(function()
	script.Parent.Notification.Text = game.workspace.PlayerJoined.PlayerName.Value .. " has joined."
	Notify()
end)
 
game.workspace.PlayerLeft.OnClientEvent:connect(function()
	script.Parent.Notification.Text = game.workspace.PlayerLeft.PlayerName.Value .. " has left."
	Notify()
end)
