I see no reason why they wouldn’t work on their side. Only thing I would worry about is the hard speaker laying on a hard surface may cause some vibration if too loud.
Yes there is a way to turn off the lights, on the one speaker you will have a power button, a volume up and a volume down button. Just click the power button and the lights will turn off but it will not turn off your speakers.
You have to plug the usb cable Into a usb port on your laptop, and plug the aux cable Into the audio port. Make sure you're not using a hub or it might not be able to draw enough power
