How can I kill all players besides the player that pressed the button?

So the point here is, that if times goes to 5, all players should die, besides the player that pressed the Button. I really don't have any idea how to make it, so i thought to come here and ask for help, Thnx!

local simonCommands = workspace.simonCommands
local theGUIs = game.Players.LocalPlayer.PlayerGui.simonCommandsOpen.CommandsGUI.simonSays
local dontmoveRemote = game.ReplicatedStorage.simonSays.DontMove



-- SIMON SAYS JUMP
theGUIs.Jump.MouseButton1Click:Connect(function()
	simonCommands.Value = "Simon Says Jump"
	print("Simon Says Jump")

	for i, v in pairs(game.Players:GetPlayers()) do
	local JumpedAlready = Instance.new("BoolValue")
	JumpedAlready.Name = "JumpedAlready"
	JumpedAlready.Value = false
	JumpedAlready.Parent = v

	for i = 0, 4 do
		i = i + 1
		print(i)
		wait(1)

	if i == 5 and v.JumpedAlready.Value == false then
			v.Character.Humanoid.Health = 0
			print("Killing: "..v.Name)
		end
	end
end
end)

local plr = game.Players.Player1

for i, v in pairs(game.Players:GetPlayers()) do
	if v ~= plr then
		-- do whatever
	end
end

Have a variable to reference the player that clicked the button. Iterate through all the players in the game, and for each player the loops goes to, make sure that the player isn't the player that clicked the button. If they aren't kill them. Otherwise, do nothing.

Try giving the player who pressed the button a BoolValue which says whether or not they clicked the button. The player you're trying to reference is game.Players.LocalPlayer.

local theGUIs = game.Players.LocalPlayer.PlayerGui.simonCommandsOpen.CommandsGUI.simonSays
local dontmoveRemote = game.ReplicatedStorage.simonSays.DontMove



-- SIMON SAYS JUMP
theGUIs.Jump.MouseButton1Click:Connect(function()
	local simon = Instance.new("BoolValue")
	simon.Name = "Simon"
	simon.Parent = game.Players.LocalPlayer

	simonCommands.Value = "Simon Says Jump"
	print("Simon Says Jump")

	for i, v in pairs(game.Players:GetPlayers()) do
		if not v:FindFirstChild("Simon") then -- checks to see if the player is not Simon/whoever clicked the button
			local JumpedAlready = Instance.new("BoolValue")
			JumpedAlready.Name = "JumpedAlready"
			JumpedAlready.Value = false
			JumpedAlready.Parent = v

			for i = 0, 4 do
				i = i + 1
				print(i)
				wait(1)

				if i == 5 and v.JumpedAlready.Value == false then
					v.Character.Humanoid.Health = 0
            				print("Killing: "..v.Name)
        			end
    			end
		else
			print("Player is Simon")
		end
	end
end)
