Question: Islamically, can a man be born twice in the world?

Answer: If what you mean is, to be born again in this world, it will suffice to say, that it is possible only by a miraculous power as has been done before; for example, Jesus (as) who gave life to the dead, and is confirmed in the Qur’an. But if you mean incarnation (holul) and the transmigration of souls (tanasukh) - whereby the soul of a dead person comes to life in another body and enters the world - then Islamically and in actuality, this is a null-and-void theory.
