Are same-sex marriages legal in states where same-sex marriage is not legal?

Yes. There are two components to the legality of same-sex marriage: (1) whether it can be legally performed; and, (2) whether it is legally recognized.

In the United States, the federal government legally recognizes same-sex marriages in all states, even if the state itself does not recognize the marriage.

There are also some states that recognize out-of-state same-sex marriages, but do not permit the legal performance of same-sex marriage within the state.
