I'm not worried about the eggs getting rolled out of the nests. The hens generally make a nest by scratching that holds the eggs well. But I'd want about a 4" or 5" lip on the bottom of those nests to keep the chickens from scratching poop and trash from the middle into those nests.
I don't see anything wrong in principle with extra roosts or nests except where they take up space you could otherwise use. I don't know how many chickens you will wind up with over time (You will need replacements as they grow older and lay less) but generally count on needing one nest for every four hens. Two nests for 8 hens, three nests for 9 hens for example. Often they only use one or two but often doesn't mean every time. Sometimes you get a hen that likes to spread out. I like the extra flexibility an extra nest can give you.
Same type of thing with roosts. I've seen a lot of different recommendations for length of roost you need per bird. I've had success with giving 9" per bird but there is nothing wrong with giving more if you have the space. If those are only 3 feet long I'd be tempted to tear the nests out and put them along the sides in the far back. Maybe along both sides.
How do you plan to gather the eggs in the nests back under the roosts? Crawl through the poop under those roosts? Personally I'd tear those nests out regardless of what else you do.
I doubt that PVC pipe was used for feed, not out in the weather like that. You want your feed to stay dry. It looks like a good place to offer oyster shell which is not affected by water. But you want it to drain, you do not want standing water in it.
