As long as it does not go around the air space at bottom, or the exhaust on top, yes.

NO! This is a FIRE HAZARD. Manufacturers of all water heaters always install insulation around the tank then cover it with the sheet metal jacket. I have seen many times where a person has insulated a gas water heater and the flames from the burner chamber escaped from the cover and ignited the plastic on the insulation blanket.

Thr R value of the water heater insulation will differ among various water heaters in various price ranges. As you can imagine a heater with 12 year warranty will be better insulated than a 5 year model.
A blanket of gases that surround a planet is called an atmosphere. its not a blanket of gas.

It doesn't change
I am considering buying a gas water heater. How does a gas water heater work?
If you are asking how you can lower your gas bill with an existing gas water heater with a tank, there are two things that you can do that will save lots of money. One is to insulate the tank with standard closed bat insulation. Simply wrap the insulation around the tank to keep the heat from escaping through the metal skin. The other way is to turn the heater down so the water isn't kept as hot, but still plenty hot for regular usage. a 10° drop in temp will save a ton of money over a year. If there are long periods of time that you do not need hot water, you can also turn off the water heater until about 30 minutes before you need it. If you are asking how a gas water heater is less expensive to use that an electric heater, this depends on your location and the price of the utilities. However a well maintained gas heater is much more efficient at producing BTUs (british thermal units) than electricity. Given similar costs of gas and electricity the gas heater will cost much less than electric over time.
Gas heater & electric heater both are available.
