For the branch sites to be able to communicate to each other via your HQ add the below config into the HQ VPN device:-

same-security-traffic permit intra-interface

This will allow traffic from branch 1 to "hairpin" to branch 2 via HQ.

That is correct - it allows access from Branch 1 to Branch 2. There is no added security from this, if you want security - I suggest you think about acl's in the inbound of the inside interface at both locations.

What services at Branch 1 and 2 would need to be used?

Are they the same company? Are they the same type of users? Do you need to limit access?
