Some of the remains recently found were parts missing from victims initially discovered dumped in Manorville in 2000 and 2003.
Authorities say the bodies are the work of at least three murderers.
Of the new remains, the first, dubbed Jane Doe Number Five, was identified as the missing body parts of Jessica Taylor.
The rest of Taylor's remains were found in 2003 in a wooded area in Manorville. Her head, hands and forearm never located at the Manorville crime scene were found March 29 along Ocean Parkway.
"It is clear that the area in and around Gilgo Beach has been used to discard human remains for some period of time," Spota said. "As distasteful and disturbing as that is, there is no evidence that all of these remains are the work of a single killer."
Taylor was dismembered, and her killer tried to remove a tattoo from her body. In investigators minds, that differentiates her killing from that of the first four Gilgo Beach victims, where no attempts were made to remove distinguishing features.
A woman's head, hands and right foot found April 4 and dubbed Jane Doe Number Six were matched by DNA to an unidentified woman also found in Manorville in 2000. The manner of disposal was similar to Taylor's and the two cases may be linked.
Jane Doe Number Seven appears to be a female.
An Asian male in his in his late teens or early 20s, identified as John Doe Eight, appears to be unrelated to the others. It also appears to be a homicide.
A toddler also found in the area was identified as a female, 18 to 24 months old. She was wrapped in a blanket and she is the only body that is not identified as a homicide.
Suffolk County District Attorney Thomas Spota said, "Clearly the area in and area Gilgo Beach has been used to discard human remains for some time. As disturbing and distasteful as that may be, it does not appear all the bodies are linked."
He added none of the remains are believed to be that of Shannan Gilbert, and the search for her body will continue.
