Could service port be the same in Kubernetes

In kubernetes, I have an application pod (A-pod), then I create a service (A-service) for this pod and expose service's port as 5678.

Now in a cluster, I have 5 namespaces, each namespace will running a service (A-service) and a pod (A-pod), so in total there are 5 A-services that are running.

My question is, because 5 A-services is using the same port (5678), does it cause conflict? How to access the different services in different namespace with service name?

Yes, it assigns each different Service name in each namespace. If you have a Service called A-service in a Kubernetes namespace your-ns, the control plane and the DNS Service acting together create a DNS record for A-service.your-ns appropriately. Refer here for more details.
