college student who needs a new laptop ASAP

I'm a student, and my 2012 i5 4gb ram macbook air is broken at the hinge causing my screen to act up so I need a replacement.

Which of these 3 are a good option for under about $700, and I don't really game except like sims haha. Please let me know the pros and con of these 3 options and which one would be worth it? And, if you know of a better computer i'd love to hear it. Looking for touchscreen, 2-in-one if possible, and I have a couple computer stores in my area such as Bestbuy and Officemax and Staples. Sorry if i'm asking a lot, I really don't know much about computers outside of Mac, but I want to explore, thus getting a windows machine!

Cheapest option, $460

The most expensive is the most desirable.
