https://www.globalsecurity.org/military/ops/where.htmReagan, Nimitz, and Roosevelt are all under active deployment, currently near Korean waters. Reagan will probably transition to a downtime cycle, she's been active and patrolling off and on for close to four years. Nimitz and Roosevelt seem fairly fresh by the look of their workups, should stick around a while.
Stennis and Truman are doing pre-deployment training and crew certifications, and without stepping into rule 4 territory I'm just going to say that recent news means they're going to spend a VERY serious time doing it. Unknown at this time how long that will take, probably not too much longer since that's been going several months already. With Reagan likely to cycle out of availability, one or both may take her place soon.
Vinson and Bush just finished their major patrols and homeported last month, there'll be some maintenance cycles and some crew shuffling as well as training in the near future. Not sure how much longer they'll be out before they go into major maintenance cycles, at least the last 3 1/2 years shows sustained major operations and nothing significant for overhaul.
Meanwhile Eisenhower is in maintenance and workup states, will return to the fleet in March for training and preparation. Lincoln just had her four year overhaul and refuel and is being restored into service, while Washington's just started its four year and won't be back until 2021 sometime, and Ford should deploy then after fitting out, training, testing, and significant workups.
