Size of sperm and egg do not determine whether or not an egg can be invaded.
According to this, it doesn't happen as often as people think:
Another variety of twins, "polar body twins," (one egg fertilized by two different sperm) is a phenomenon that was hypothesized to occur and may recently have been proven to exist. Polar body twinning would result in "half-identical" twins
When two eggs are independently fertilized by two different sperm cells, fraternal twins result.
Identical twins occur when a single egg is fertilized by one sperm to form one zygote which then divides into two separate embryos.

No, one egg one sperm, the egg will not use more then one sperm. twins are from two eggs or the egg splits during cell division.

yup, that's how twins become. If three sperms get into one egg, they're called triplets. But these are same egg twins or triplets so they look exactly the same, different egg twins and triplets don't look alike.

i dont think so
but twins often are a result of a woman releasing multiple eggs at once and them getting fertilized

Females only have eggs.
Yes, they are called twins.
