Requirement is, internally we can maintain N number of namespaces(net), but we are exposing one namespace(default) which will communicate with external system and with other N namespaces (processes inside the these should not communicate but only with default namespace).

What does that mean?

When you say "namespace", there's the mount namespace, network
namespace, PID namespace, /dev namespace, and several others.  Each can
be individually unshared, meaning siblings processes can see the same
network but different filesystems and neither of them have the full
device list their parent has.

As for "communicate": they can communicate.  You can set up a network
routing between different network namesapces.  You can mount shared
filesystems between different filesystem namespaces.  You can
communicate to the outside world through /dev nodes in a unique device

Please explain: what are you trying to _do_?
