Hi Sarang,
AFAIK, data import between AEM and Campaign server, is a one way operation. That is, you can send data from AEM to Campaign but I don't think you can pull data from the Campaign server.
That being said, since the recipients information in campaign server is usually imported from an external source, that might be a database or a CRM system, you can write a simple importer in AEM to import the recipients profiles in AEM.
I hope this helps.
