Pretty good shots.
I like the pic with Ny as a backdrop.
Lens -Get a 50mm F1.8 fixed lens. They are cheap and will get better low light night time shots.
Did you tripod your camera or put on a fixed surface?
Maybe put the camera on a timer and take shot so that pressing the button won't move it.
Try some different exposure settings.
