Almost any thermostat out there will control multiple heat sources, but if you are talking about independent control - ie cage 1 at 90, cage 2 at 84 etc. - then as mentioned you would need a Herpstat 4.
Otherwise, you can use almost any t-stat. I recommend the Johnson or Ranco at the lower end and the Herpstats at the higher. I've used both for many years and they're great.

As long as they are all identical (heat source/cage/substrate) and you understand the risk involved.
