It depends on the incarnation of superman. Generally one must assume Lois to be as old as Clark or alittle older due to her being a top level Journalist buy time superman comes to Metropolis. In the 90s animated series, Lois was a few years older then superman. In Lois and Clark, she was about the same age as clark/superman. In the old christopher superman Reeves films, she was younger then superman [even though she looks older then him]. As you can tell every incarnation of superman does its own thing with their ages.
