Credit for other dependents & HOH Question

[artp]

Single taxpayer is sole support for live in girl friend (not related) and her 13 year old son. Girl friend has no income. She and her son lived with the taxpayer all year. Father of the 13 year old is incarcerated. Can taxpayer claim $500 credit for both the girl friend and her son?  

Taxpayer also has an adopted daughter age 3 who he fully supports and lives with him all year. So HOH status?

The adopted daughter qualifies him for HOH.  The other two qualify as "Other"  or Qualifying relatives.

Thanks for the confirmation. These situations always confuse me.
