Ai following one player please help?

I´m creating a horror game, i created a mian script who works for all ai on a folder but i have a problem it follows only one player and ignore the others players

local Distance = 40

local Damage = 100	

local scaryimg = game.ReplicatedStorage:WaitForChild("ScaryPlayer")

local candamage = true

local Wander = true
local WanderX, WanderZ = 10, 10

	spawn(function()
	
	function getHumanoid(model)
		for _, v in pairs(model:GetChildren()) do
			if v:IsA'Humanoid' --[[v:FindFirstChild("Humanoid")]] then
				return v
			end
		end 
	end
	
	local zombie = Monsters

	local human = getHumanoid(zombie)
	local hroot = zombie:FindFirstChild("HumanoidRootPart")
	local zspeed = hroot.Velocity.magnitude

	
	local pfs = game:GetService("PathfindingService")
	
	function GetPlayerNames()
		local players = game:GetService('Players'):GetChildren()

			if v:IsA'Player' then
				name = tostring(v.Name)

	end
	function GetPlayersBodyParts(t)
		local torso = t

			local figure = torso.Parent

Help me please i need this urgently Thanks

i Tried make something similar like you said me but i don´t works:

--New Code

function GetTorso(pos)
		local char = game.Workspace:children()
		local torso = nil
		local Id = nil
		local human = nil
		local Ad = nil
		for ea = 1, #char do
			Ad = char[ea]
			if (Ad.className == "Model") and (Ad ~= script.Parent)  then
				Id = Ad:findFirstChild("Torso")
				local charRoot = Ad:findFirstChild("Humanoid")
				if (Id ~= nil) and (charRoot ~= nil)  then
					if (Id.Position - pos).magnitude < SearchDistance then
						torso = Id
					end
				end
			end
		end
		return torso
	end

please help me with this thanks

sorry im so noob with the pathfinder
