Welcome to Android Central! Can you clarify your question? Are you having difficulty adding phone numbers to a specific contact? Or are you having difficulty creating a new group?

I find it easiest to manage groups in Google Contacts on the web. But in the Contacts app, you can select a contact, tap Edit, scroll down to the groups field, and either select an existing group, or Create a New Group.
