Sorry! I didn't see you edited your main post. I've never used Packet Tracer to the extent that you're using it so we're learning together. What Kasun was trying to lead you to is the "Physical" view of your network. If you look about your network layout you'll see two buttons, one that says "Logical" and one that says "Physical". Going to the Physical layout on your setup reveals one city, "Home City". Clicking on "Home City" reveals one location "Corporate Office". When I first looked at Corporate office everything was in the top left corner so I spread everything out to get a grasp on what I was seeing. What we're primarily concerned about is the "Main Wiring Closet" and "Wiring Closet". All of your APs except for one are in the main wiring closet. All but two of your routers are in the same closet. To get the results you're looking you need to physically separate all of your branches. Again, I don't have any experience with that but I'm going to mess with it so feel free to reach out if you get stumped.
As for routing, that's too deep for a forum post but if you wanted a quick proof that all of your connections and IPs are working as they should you could just run something like "router eigrp 1" "network 0.0.0.0" on all of your routers and work on limiting it from there.
