The largest inferno - the so-called "Camp Fire" in the foothills of the Sierra Nevada mountains north of Sacramento - has destroyed 6,700 homes, business and other buildings in the town of Paradise, effectively wiping it off the map.
Butte County Sheriff Cory Honea said the human remains recovered on Sunday included five bodies found at homes and one in a vehicle in Paradise.

Hundreds of kilometres to the south, at least two people died in the Woolsey blaze, which is threatening the wealthy beach community of Malibu, near Los Angeles.
Los Angeles County Fire chief Daryl Osby told reporters of his gratitude to firefighters "who've done all they could do save tens of thousands of people's lives and thousands of people's homes".
"Unfortunately, the best science is telling us that the dryness, warmth, drought, all those things, they're going to intensify", he said.
He said the footprint of the Woolsey Fire contains many unburned areas that are vulnerable to embers stoked by gusts that could reach 64kmh.
More than 200 people remain unaccounted for, according to authorities, meaning the event is poised to become the deadliest wildfire in the state's history.
A fire truck stands by as the Camp Fire burns in the hills on November 11, 2018 near Big Bend, California. "We do not want any more lives lost".
Since the spread of these fires, over 20,000 residents had to flee from their homes, The Washington Post reported.
In southern California, more wildfires burned, including one just north of Los Angeles and another in Ventura County near Thousand Oaks, where a Marine Corps veteran shot dead 12 people in a country music bar on Wednesday.
The rocker also revealed that his own home near Malibu had been destroyed in the blazes that have thus far caused historic damage in both northern and southern California. "We're putting everything we've got into the fight against these fires and this request ensures communities on the front lines get additional federal aid", Brown said in the release.
As of Sunday, the Camp Fire had blackened more than 109,000 acres at the edge of the Plumas National Forest.
Hot dry winds expected to blow until Tuesday whipped up the flames and heightened the urgency of evacuation orders, officials said.
The first fatality of the California wildfires has been identified as an ailing woman who was found dead in her bed in her burned-out northern California home.
Ellen Walker, who was in her early 70s, was home alone when the fire struck on Thursday, according to Nancy Breeding, a family friend.
Walker's husband was at work and called a neighbor to check on his wife and tell her to evacuate, Breeding said. Authorities confirmed her death late Friday.
He described an even drier, warmer climate that could make such devastating wildfires more common than in past years.
