How do I get the names of all children?

So I'm making a gui that will display all of the pieces of a player on a surface gui. I also have it printing them. I got it to do it, but it does them individually. So the gui will display only one of them. How do I get it to either display all of them, or display each of them on different text labels? Here is my gui so far:

script.Parent.Touched:connect(function(hit)
    if hit.Parent:FindFirstChild('Humanoid') then
    local children = hit.Parent:GetChildren()
    for index, children in pairs(children) do
        print(index, children.Name)
        game.Workspace.List.SurfaceGui.Frame.TextLabel.Text = children.Name
        game.Workspace.List.SurfaceGui.Frame.TextLabel.TextSize = 5
    end
end
end)
