Hey Kevin, you apparently have an AT&T Axia model. It's running Android Go, a version of the Android operating system created specifically for lower-spec models. You might have the paper form of the user manual already (came with your phone) but here's a link for the PDF version:

... and just for your reference, here's a couple of links showing the general hardware specifications of your phone. It could come in handy later:

Regarding the cable you're using, just use the one that came with your phone. And it's not a matter of the cable damaging your phone, just don't plug the cable into places you don't know is on the other end. Just use the power adapter that came with your phone to charge it. Or use the USB port on a computer or laptop in your own home.
The cable itself is referred to as a USB cable. There are established standards so it's more a matter of if the cable doesn't fit into your phone's USB port it's not the right type. Don't try to force it, generally there's just a little resistance to set it in place. Again, just use the cable that came with your phone.

Use your phone for a while and get used it. After a day or two, sit down and go through the Settings menu. Go through each option and this will get you more familiar with all the different options your phone is capable of. Different phone models have different capabilities and the Settings menu will directly reflect that.
And don't make a lot of changes in your Settings all at once, you might inadvertently disable important features or those you need to use. Just keep track of the ones you do alter so if you do turn off something you need you can just turn it back on again.

It's not a big deal at all really. At any given point in time I'm never sure about my own identity anyway. ;-)
