Help limiting spawning characters

Help and Feedback Scripting Support
#1

Hello! i had someone help me make a script about spawning a friends character, however i only want it to spawn however many parts are in a folder. For example: 5 parts in a folder, 5 characters to spawn.

Also, i want it to only spawn them if the part is empty and not spawn them at a part where another character is.

Can anyone help me do this?

Code:

task.wait()
function SpawnFriend() 
	local PlayersService = game:GetService("Players")
	local LocalPlayer = PlayersService.LocalPlayer
	local FriendIDs = {}

	local success, fail pcall(function()
		local friendsList = PlayersService:GetFriendsAsync(LocalPlayer.UserId) 

		for page=1,4 do 
			for _,friend in pairs(friendsList:GetCurrentPage()) do 
				table.insert(FriendIDs, friend.Id)
			end

			if page ~= 4 then 
				local pass,err = pcall(function() 
					friendsList:AdvanceToNextPageAsync()
				end)

				if not pass then 
					break 
				end

			end
		end
	end)

	task.wait(0.1)

	local Parts = workspace:WaitForChild("A"):GetChildren()

	local function GetRandomFriend()
		return FriendIDs[math.random(1, #FriendIDs)]
	end

	for i,v in pairs(Parts) do
		v.CanCollide = false
	end
	
	
		local SelectedFriend = GetRandomFriend()
	local FriendCharacter = PlayersService:CreateHumanoidModelFromUserId(SelectedFriend)
	
		FriendCharacter:PivotTo(Parts[math.random(1, #Parts)].CFrame)
		FriendCharacter.Parent = workspace	
end

while true do
	local success, err = pcall(SpawnFriend)
	task.wait(0.1)
end
