I don't know of a single timer that has 4 individualy timed plugs.
Coralife has a 'digital' one that has 8 plugs(I think it's

where 4 are on and 4 are off and you can set it so they flip back and forth once a day, as in 12 hrs on and 12 hrs off, not limited to 12 hrs though.
Mine broke after about a year so I bought 4 individual mechanical timers, the kind with the little red and green pins, for less than the cost of a new Coralife. I like them better anyway cuz I can get extra pins and set as many on-off cycles as I want on each timer. Although I must say any more than 3 cycles would be over kill.
