Only if you know what the blacks are for. Unfortunately one of your blacks (the one that used to have the red sleeve) is a switched live. If you connect that to a black that is a neutral and switch on, then BANG!.I've also seen advice saying never to put 2 blacks together!
So, you really need to find which of those blacks had the red sleeve........
But that is for light #3. For light #1 follow EFLI's advice, but only after testing first.
