Yes, with work and luck (the usual), you should get ≥1 lb. in a 3x3 (9 sq. ft.) tent.  Presuming 18" square or 2.25 sq. ft./plant as an experienced grower you should be able to get about 2 oz./sq. ft or ≥1/4 lb./plant in this size range (although I'm assuming using coco or other non-soil medium; presume somewhat less if using soil).  Crowded in like this, don't expect or try to grow very tall plants.
	
		
			
		
		
	
				
			 
	 
 
		 
			
		
		
		
		 
 
		 
			
		
		
		
		 , you can get some nice yields from the autos, I runa pair of lights in 2x4 for a total draw of 240W from the wall using Migro Arays. Typical yields if the space is maxed out growing scrog will see 2 plants yield 850g+ for 3grams a watt or even slightly more.
