Can resources have same names across namespaces?

Yes, resources can have the same names across different namespaces in Kubernetes. This is one of the key features of namespaces, as they provide a way to avoid name collisions. For example, you can have a pod named web in both the dev and prod namespaces without any conflict. Each resource is uniquely identified by its name within its namespace, but the same name can exist in multiple namespaces simultaneously.
