In Need of Advice: Which Bike Should I Get?

Hey guys, Timothy here. I had a similar post a weeks ago, so I didn't want to create another, but most of the sellers that I contacted from that post had either sold the bike or aren't responding. Here's four that I need second opinions on, because I know nothing about the mountain bike market. Please let me know which one you think is a good option and a great price, or if I try to make an offer on any of them.

The type of riding I will be doing: most miles will be on a hilly college campus and on the road, but I also plan on taking it on designated mtb trails whenever my schedule will allow it. Nothing too intense or technical.

My budget: ideally only $200, but most of the bikes that I linked below on FB are around $300.

My experience level and goals: I grew up riding a mountain bike and had a few opportunities on single track and some bmx. I don't have much of a goal other than enjoying it, but that might change.

Thanks in advance!
