No. First Isaac isn't even a hurricane yet (as of August 27, 2012). It is still a tropical storm. Even though Isaac is a very large storm it is still not as large as Katrina. Based on forecasts Isaac probably won't get any stronger than a category 2 hurricane. Katrina was a category 5.

There is no such things as "a Katrina hurricane." Hurricane Katrina was a particular hurricane that hit the Gulf Coast in 2005. Hurricane Katrina was worse than any tornado on record and deadlier and more destructive than any recorded snowstorm. Katrina was worse than most earthquakes, but not all. Hurricane Katrina killed about 1,800 people. Some earthquakes have had death tolls in the hundreds of thousands.
Hurricane Andrew wasn't as bad or as strong as Katrina, if that's what you mean.
Hurricane Rita formed a little less than a month after Hurricane Katrina.
The Galveston hurricane was actually far deadlier than hurricane Katrina. Estimates of the death toll range from 6,000 to 12,000. By contrast the death toll from Hurricane Katrina was about 1,800.
The total energy in a hurricane is considerably more than that released by even the largest nuclear bombs. However, the energy of a bomb blast is much more concentrated.
No. The Galveston hurricane killed several times more people then Hurricane Katrina.
