Dozens of "rest in peace" and "heartfelt condolences" messages poured into the women's Facebook sites.
Four passengers and the driver survived Saturday night's deadly inferno that erupted as the women headed into San Francisco to celebrate the nuptials of Neriza Fojas, who died in the blaze.
The cause of the fire, captured on camera as a blast of flames at the back of the white stretch limo, is under investigation.
Fojas, 31, and another victim Michelle Estrera, 35, were both nurses at Community Regional Medical Center in Fresno.
Victims Jennifer Balon, a 39-year-old mother of two, and Anna Alcantara, 46, both worked at Fruitvale, while Felomina Geronga, 43, also a mother of two had been working at Kaiser Permanente Medical Center in Oakland.
John Balon, whose wife Jennifer went by the nickname Jenni, told the San Francisco Chronicle that their 10-year-old daughter Jillian cries for her mother at night and is working on paintings to give her for Mother's Day. His daughter and 1-year-old son are still looking for their mother, he said.
He told his daughter that she is in heaven.
"I told her mom doesn't want us to worry a lot," he told the Chronicle. "She is happy there. She won't be happy if we worry."
Jennifer Balon's Facebook page reflects her love for her children, with photo after photo of them playing, laughing and hugging.
On Tuesday, condolences from around the world poured in.
"Jen, things will never be the same again. We are so devastated that we lost you this soon," wrote her friend Willen Berdos, also an East Bay nurse.
Three survivors hospitalized were identified as Jasmine Desguia, 34, of San Jose; Mary Guardiano, 42, of Alameda; and Amalia Loyola, 48, of San Leandro. Nelia Arellano, 36, of Oakland, was treated and released.
The survivors managed to squeeze through the partition after the driver pulled over and climbed out. The victims were found pressed up against the partition.
