Answer
I will tell you how to set the tank for the corn snake and that if the milk snake and/or the king come from a habitat similar to the corn you could do it the same way.   But!  If the milk or the king come from a different type of habitat you'll have to adjust.  When you say corn snake, we are talking about one species.  When you say milk or king snake, we are talking about entire Genuses with many species in each, so variation would come into play.

If you are buying baby snakes, I perfer the plastic "Kritter-keeper" type cages because the lids lock down very tightly.  

If you are buying adults, a 20 gallon long with a tight fitting lid will work fine.  Aspen bedding, newspaper, or indoor/outdoor carpet are all good for substrate. DO NOT use other wood or organic products as there can be problems.  A water dish large enough for them to get into. A hidebox/cave of some sort.  They should be fed 1-2 prey items per week.  Prey items should be as big around as they are - MEASURED AT THE SNAKE WIDEST POINT- not it's neck, but the widest point of the body.  Basic rule baby snakes eat baby mice, half grown snakes eat half grown mice, adult snakes eat adult mice.  Temperature mid 80's during the day (hot end) mid 70's (cool end) at night you can drop 10-20 degees, also during the winter depending on species-you'll have to research the species individually.  Try to handle at least weekly and try not to feed in the cage in which they live - use a paper bag or another cage - cuts down on nipped fingers!
