You bet, as some could even be much larger and better than Earth, with near perfect climates, with almost endless resources. Some could be slightly cooler for those that prefer cool climates, and some warmer, for those that like hotter climates.
Many will resemble our earth's Death Valley with atmospheres of cyanide, and many will look like Antarctica, but you can bet, there will be some that are truly a paradise for humans.
Being hundreds of millions of light years away, no on earth has a clue what is there, and it's my opinion and belief, that there is not only life, by life beyond our wildest imaginations.
