what is the difference between sawzall 2821-20 & 2722-20??

Not sure one could have a brush-less motor.

Does it come with a case?

No, tool only. Cases are expensive for these, might find on ebay.

What is the overall length of the tool??

Total tool length 17.1" Brand Name: Milwaukee Sub Brand: M18 FUEL SAWZALL Product Type: Reciprocating Saw Adjustable Shoe: Yes Battery Type: Lithium Ion Brand Name: MILWAUKEE Corded or Cordless: Cordless Electric Brake: No Keyless Blade Change: Yes Length of Stroke: 1-1/4 inch Strokes per Minute: 3000 Strokes per Minute Sub Brand: M18 FUEL SAWZALL Switch Type: Variable Volts: 18 volt Tool Weight: 6.8 pound Tool Length: 17.1 inch Brushed or Brushless: Brushless

Will m18 red lithium xc 5.0 battery work with this

Yes. That is a M18 Fuel SAWZALL. The XC 5.0 will last longer. Make sure you buy a battery with the Milwaukee trademark on the battery. They have cheap knock offs but they are not worth it.
