If a guy ejaculates twice inside would that produces twins?

No. Each ejaculate contains hundreds of millions of sperm, twice as many will not make more babies. Also note that it's not only the sperm that matter, it's also the eggs inside the woman.

Only rarely do the ovaries release multiple eggs, resulting in fraternal twins.
