Hey there!
Photo #2:
You have a really slow shutter speed and your widest aperture for that zoom so thats good - and i assume you've used a tripod.
Only thing i can say is to maybe put your ISO to 400 or even 800 to help pick out the lights more and if you had used the wide angle setting you could have got a wider aperture, so to make the photo brighter.
The only thing i can say for #3 is that shutter speed is a little too fast for that light, id have maybe used 2 seconds but just play around with the shutter speed till you find whichever photo looks best.
But im only learning as well, so i hope what i have said has helped you!
Cheers
