Some of the dozens of families were seen Saturday in the capital, Abuja, where the girls were taken by Nigerian authorities after their release early this month.
It was the largest liberation of hostages since 276 Chibok schoolgirls were abducted from their boarding school in 2014.
Five commanders from the extremist group were exchanged for the girls' freedom, and Nigeria's government has said it would make further exchanges to bring the 113 remaining schoolgirls home.
The mass abduction in April 2014 brought international attention to Boko Haram's deadly insurgency in northern Nigeria, and it launched a global Bring Back Our Girls campaign that drew the backing of some celebrities, including former US first lady Michelle Obama.

Thousands have been kidnapped during the extremists' eight-year insurgency, and more than 20,000 have been killed. The release of the 82 schoolgirls this month came after an initial group of 21 girls was released in October. Nigeria's government has acknowledged negotiating with Boko Haram for their release, with mediation help from the Swiss government and the International Committee of the Red Cross.
Both groups of freed girls have been in government care in the capital as part of a nine-month reintegration program that President Muhammadu Buhari has said he will oversee personally. But human rights groups have criticized the government for keeping the young women so long in the capital, far from their homes.
