Theoretically no, but I found this on the net. Other Types of Twins While identical and fraternal twins usually hog the spot light, there are a few other types of twins that are equally intriguing. Conjoined ("Siamese") twins are those that are attached at birth. Half identical twins, or polar body, occur when one egg splits in two before fertilization. Each half is then fertilized by a separate sperm. These twins share 75% of their DNA as they share the same DNA from one egg and different DNA from each sperm. THERE IS A RARE INSTANCE Semi Identical Twins
The 'semi-identical' twins are the result of two sperm cells fusing with a single egg, before becoming two embryos. An embryo created this way doesn't usually survive, but a few cases are known. Most of the time it goes totally unnoticed, and only shows up either if the two eggs have different genetic genders and the baby ends up with a mix of male and female gonads, or if it happens to be picked up on a genetic test that's done for other reasons (ex. paternity tests).

Identical twins start out just like a normal fertilised egg (one egg and one sperm), but in the early development the embryo splits.

How many eggs and sperm's are used create identical twin?
One egg, one sperm.
How many sperm cells can fertilise a egg?
Only one sperm cell can fertilise each ovum. After that no more can get in.
Can a woman be impregnated by two different man and have twin baby's from them?
No. Only one sperm cell can fertilize an egg. One of them is the father. Not both
Usually one egg is fertilized by one sperm?
because a "wall" is put up when the sperm meets the egg. This prevents another sperm from meeting the egg.
What happens when the sperm enters an egg?
It takes many sperm to break the outer barrier of the egg, but only one to fertilize it. When that sperm meets the egg, their genetic material (chromosomes) combine to form 46 and the fertilized egg, zygote, beings to rapidly divide into a blastocyst. After about two weeks it is called an embryo, and after eighth weeks a fetus. After about 40 weeks, it is born and is called an infant.

What is conceiving?
Conceiving is the process in which the egg and sperm meet together and become one. Once conceived it travels down the Fallopian tubes into the uterus.

No. Only one sperm cell can fertilize an egg. One of them is the father. Not both

How many sperm cells unite with the egg?
One because the sperm is one cell and the egg is one cell

What happen 2 sperm had entered the egg?
An egg only allows one sperm to enter and is fertilized by that one sperm: 2 cannot enter.
Why do you think millions of sperm are released to fertilize one egg?
a man can release millions of sperm at once,however only one sperm can fertilize an egg
Can two sperm cell unite with egg cell?
Two sperm, one egg - no. Two sperm, two eggs - yes.
Can more than one sperm reach an egg?
It's not possible, because after one sperm cell reaches an egg, the egg cell slightly changes look to keep other sperm cells from reaching the same egg.
Why does the egg covering change after a sperm has entered the egg?
The outer layer of the egg changes to prevent more than one sperm from entering the egg.
