You can Create a Contact Group on iPhone and Add Contacts to Group by using Contacts App and also by going to your iCloud Account on the Web.
The advantage of grouping similar Contacts in a Contact Group is that it allows you to address Text Messages and Emails to the Group Name, which saves you the effort of manually selecting individual Contacts in a Group Message.
Before going ahead with the steps to Create Contact Group on iPhone, make sure that the Contacts App on iPhone is provided with access to iCloud.
Open Settings > tap on iCloud > Show All > On the next screen, move the toggle next to Contacts to ON position.
After this, you will be able to Create Contact Groups and add Contacts to Contact Groups, right on your device.
