Yes
Do these cars have lots of problems?
Nope.
What's the max mpg you can get with this car?
Depends on how you drive.
Can this get slightly more than 31 MPG?
Yes. 31.1. What kind of question is that?? What if you get 32?? In the big picture, that's pennies per month man. It'll get 31 if you don't drive like a typical little kid.

No, they are the same.
Would this be expensive to insure
No more expensive than any other 4 cylinder car (Civic, Corolla, Sentra)
ALLLLL this information is available to you online. You can ask a question on here, but you cannot do your own research??
Since you are incompetent, let me do it for you:
Mazda is #2 on Consumer Reports for reliability. Ahead of Toyota and Honda. Mazda's hold their value VERY well. It's as safe as you can get for a small car. Just do you own research an quit being lazy hoping we do it for you.
