How would i solve this loading from datastore issue?

i have a multipliers shop that basically multiplies the amount of x the player earns when they collect an item ( coins, etc) but when it saves the data it saves to the player properly, however the loading portion is the messed up part. It loads into rep storage and for the first player thats great however when theres more than 1 player it messes up and replicates the first player's multipliers to everyone else. Should i save a value to a table and then set it to the bool value? where would that bool value end up? in rep storage, server storage, or the player themselves? i have alot of unknowns when making this script, i wanted to tackle a harder script for myself but i think i bit off more than i can chew

local replicatedstorage = game:GetService("ReplicatedStorage")
local remotecoins = replicatedstorage.Multipliers.CoinsMultiplier
local remotecoils = replicatedstorage.Multipliers.CoilsMultiplier
local remotepetluck = replicatedstorage.Multipliers.PetLuckMultiplier
local datastore = game:GetService("DataStoreService")
local multipliers = datastore:GetDataStore("Multipliers")

game.Players.PlayerAdded:Connect(function(player)
	local data1
	local data2
	local data3
	local data4
	local data5
	local data6
	
	local success, errorMessage = pcall(function()
		
		data1 = multipliers:GetAsync(player.UserId .. "-Springsx")
		data2 = multipliers:GetAsync(player.UserId .. "-Coinsx")
		data3 = multipliers:GetAsync(player.UserId .. "-PetLuckx")
		data4 = multipliers:GetAsync(player.UserId .. "-SpringsCost")
		data5 = multipliers:GetAsync(player.UserId .. "-CoinsCost")
		data6 = multipliers:GetAsync(player.UserId .. "-PetLuckCost")
		print(data1)
		print(data2)
		print(data3)
		print(data4)
		print(data5)
		print(data6)
	end)
	
	if success then
		print("Success, loaded multipliers")
		print(data1)
		print(data2)
		print(data3)
		print(data4)
		print(data5)
		print(data6)
		
		if data1 and data4 then
			remotecoils.Multiplier.Value = data1
			remotecoils.MultiplierCost.Value = data4
			
		else
			remotecoils.Multiplier.Value = "1"
			remotecoils.MultiplierCost.Value = "100"
		end
		if data2 and data5 then
			remotecoins.Multiplier.Value = data2
			remotecoins.MultiplierCost.Value = data5
		else
			remotecoins.Multiplier.Value = "1"
			remotecoins.MultiplierCost.Value = "100"
		end
		if data3 and data6 then
			remotepetluck.Multiplier.Value = data3
			remotepetluck.MultiplierCost.Value = data6
		else
			remotepetluck.Multiplier.Value = "1"
			remotepetluck.MultiplierCost.Value = "1000"
		end
	else
		print(errorMessage)
		
		remotecoils.Multiplier.Value = "1"
		remotecoils.MultiplierCost.Value = "100"
		
		remotecoins.Multiplier.Value = "1"
		remotecoins.MultiplierCost.Value = "100"
		
		remotepetluck.Multiplier.Value = "1"
		remotepetluck.MultiplierCost.Value = "1000"
		
	end
end)


game.Players.PlayerRemoving:Connect(function(player)
	
	local coilsx = remotecoils.Multiplier.Value
	local coinsx = remotecoins.Multiplier.Value
	local petluckx = remotepetluck.Multiplier.Value
	local coilsc = remotecoils.MultiplierCost.Value
	local coinsc = remotecoins.MultiplierCost.Value
	local petluckc = remotepetluck.MultiplierCost.value
	
	local success, errorMessage = pcall(function()
		multipliers:SetAsync(player.UserId .. "-Springsx", coilsx)
		multipliers:SetAsync(player.UserId .. "-Coinsx", coinsx)
		multipliers:SetAsync(player.UserId .. "-PetLuckx", petluckx)
		multipliers:SetAsync(player.UserId .. "-SpringsCost", coilsc)
		multipliers:SetAsync(player.UserId .. "-CoinsCost", coinsc)
		multipliers:SetAsync(player.UserId .. "-PetLuckCost", petluckc)
	end)
	
	if success then
		print("Saved Data Successfully")
	else
		print(errorMessage)
	end
		
end)
	
game:BindToClose(function()
	wait(7)
end)

any help would be great, im just hoping that the problem isnt too great and its something small like what i mention in terms of it being just replacing what the value is saved to and where.

Okay okay, where to start where to start...

First and foremost you should be using one datastore, and one key for each user. Secondly, you are not separating out each player when you save/load their stats.

I have rewritten your script to suit the above.

Please bear in mind, this code is 100% untested so modification may be necessary.

local datastore = game:GetService("DataStoreService")
local mutliplierDatastore = datastore:GetDataStore("Multipliers")

game.Players.PlayerAdded:Connect(function(player)
    local playerData

    local success, errorMessage = pcall(function()
        playerData = multipliers:GetAsync(tostring(player.UserId))
        print(playerData)
    end)

    local CoilsMultiplier = Instance.new("IntValue");
	CoilsMultiplier.Name = "CoilsMultiplier";
	CoilsMultiplier.Parent = player;

    local CoinsMultiplier = Instance.new("IntValue");
	CoinsMultiplier.Name = "CoinsMultiplier";
	CoinsMultiplier.Parent = player;

    local PetLuckMultiplier = Instance.new("IntValue");
	PetLuckMultiplier.Name = "PetLuckMultiplier";
	PetLuckMultiplier.Parent = player;

    local CoilsCost = Instance.new("IntValue");
	CoilsCost.Name = "CoilsCost";
	CoilsCost.Parent = player;

    local CoinsCost = Instance.new("IntValue");
	CoinsCost.Name = "CoinsCost";
	CoinsCost.Parent = player;

    local PetLuckCost = Instance.new("IntValue");
	PetLuckCost.Name = "PetLuckCost";
	PetLuckCost.Parent = player;

    if success and playerData ~= nil then
        print("Success, loaded multipliers")
        print(playerData)

        CoilsMultiplier.Value = playerData["CoilsMultiplier"] or 1
        CoinsMultiplier.Value = playerData["CoinsMultiplier"] or 1
        PetLuckMultiplier.Value = playerData["PetLuckMultiplier"] or 1
        CoilsCost.Value = playerData["CoilsCost"] or 100
        CoinsCost.Value = playerData["CoinsCost"] or 100
        PetLuckCost.Value = playerData["PetLuckCost"] or 1000
    else
        print(errorMessage)

        CoilsMultiplier.Value = 1
        CoinsMultiplier.Value = 1
        PetLuckMultiplier.Value = 1
        CoilsCost.Value = 100
        CoinsCost.Value = 100
        PetLuckCost.Value = 1000

    end
end)


game.Players.PlayerRemoving:Connect(function(player)

    local playerData = {}
    playerData["CoilsMultiplier"] = player.CoilsMultiplier.Value
    playerData["CoinsMultiplier"] = player.CoinsMultiplier.Value
    playerData["PetLuckMultiplier"] = player.PetLuckMultiplier.Value
    playerData["CoilsCost"] = player.CoilsCost.Value
    playerData["CoinsCost"] = player.CoinsCost.Value
    playerData["PetLuckCost"] = player.PetLuckCost.Value



    local success, errorMessage = pcall(function()
        mutliplierDatastore:SetAsync(tostring(player.UserId), playerData)
    end)

    if success then
        print("Saved Data Successfully")
    else
        print(errorMessage)
    end

end)

game:BindToClose(function()
    wait(7)
end)
