How do I make a loop that repeats?

game.Workspace.NameMaker.Touched:Connect(function(hit)
    local player = game.Players:GetPlayerFromCharacter(hit.Parent) --instead of getting player from the join event which only happens once until the player rejoins the game, you can get it from the character when it touches the part
        local hum = hit.Parent:FindFirstChild("Humanoid")
        if player and hum then
            game.Workspace.MyFavPart.SurfaceGui.TextLabel.Text = plr.Name .. " Is cooler lol"
    end
end)

That a look at this article made by Roblox

You can use:

for, which I don't think it's what you want

for i = 1, 10, 1 do
    print("Hello, world!")
end

-- Output: Hello, world! (x10)

while, which I think it's what you might want

while wait() do -- you can also use while true do wait()
    print("Hello, world!")
end

-- Output: Hello, world! (xForever!)
-- (Only stops if the value after while is false)

repeat until loops

repeat
    print("Hello, world!")
until false

-- Output: Hello, world! 
--  (Only stops if the value after until is true. it is always executed at least once, even if it the condition is false)
