Which of the Companions was born in Mecca?

Perhaps the questioner is referring to someone born inside the Kaaba, who is Hakeem ibn Hizam, may Allah be pleased with him. No one else was born inside the Kaaba besides him. However, if the intention is to ask about those born in Mecca, then many Companions and Qurayshis were born there, including the four Rightly Guided Caliphs and the ten who were promised Paradise.
