Polycephaly is a condition of having more than one head. The term is derived from the Greek stems poly- meaning 'much' and kephali- meaning 'head', and encompasses bicephaly and dicephaly (both referring to two-headedness). A variation is an animal born with two faces on a single head, a condition known as diprosopus. In medical terms these are all congenital cephalic disorders.
There are many occurrences of multi-headed animals, in real life as well as in mythology. In heraldry and vexillology, the double-headed eagle is a common symbol, though no such animal is known to have ever existed.
Bicephalic or tricephalic animals are the only type of multi-headed creatures seen in the real world and form by the same process as conjoined twins: they all result from the failed separation of monozygotic twins. –Wikipedia
Abigail Loraine Hensel and Brittany Lee Hensel (born 7 March 1990, Minnesota, United States) are dicephalic conjoined twins. Brittany ("Britty") is the left twin, and Abigail ("Abby") is the right twin. They have two spines which join at the pelvis. They have two stomachs, three lungs, and at birth, three arms (the arm between their heads was underdeveloped and useless, and was amputated in infancy).– Wikipedia

An Argentine woman has given birth to conjoined twin girls and a boy. The twins were born fused at the head, and shared a heart and other vital organs. The woman also delivered a healthy baby boy.
The birth occurred in the provincial city of San Juan, Doctor Gonzalo Medina told the Todo Noticias cable news channel. He said the girls were born joined from the chest to mid-abdomen and shared other lower parts of the body. He said the twins, born as part of triplets with the boy, are in a stable condition. He said an initial assessment indicated it may not be possible to separate them. But he added that his staff are consulting with surgical teams in other countries. The mother, who was not identified, is in a stable condition, Medina said.
Conjoined twins occur when a single fertilized egg splits to form twins, but the separation is incomplete. They occur about once in every 200,000 live births and are three times more likely to be girls than boys.
