Do they have exchange 5 gallon water bottles?

Yes they do

They do have a place in the back by the milk in the tea and everything in the way in the back corner if I'm correct on this Walmart it's changing the water jugs, but I would recommend going to the place where you can get like fresh ice that's pure a fide and great purified water and there's like a couple of them one in the family video on 15th and Gage will used to be Family Video now it's Marco's Pizza in Dollar General it's in the parking lot and they only charge you a dollar and you get the whole 5-gallon jug filled up on top of that the ice is really cheap that you give you can get there and it's really good just saying it's better than the Walmart one my personal pain but Walmart is getting a lot better.

Yes they do. Towards the back in food section
