The cylinder head may be cracked between cylinders 2 and 3 or there may be a "low" spot between those two cylnders, did you have the cylinder head checked out and resurfaced while you had it off? It's always best to take the cylinder head to an automotive machine shop for a leak test, resurfacing, and a valve job while it is off.

Does engine need to be replaced when there is no compression?
If there is NO compression on any of the cylinders, you've probably slipped the timing belt/chain. Just knowing that there is no compression is insufficient information to make a decision about replacing the engine. You COULD need to have the engine rebuilt, or it's possible that a valve "kissed" a piston and the engine is toast. Or... it could be something else. If it's just low compression in one or two cylinders, it could even be caused by burned or sticking valves.

How do you fix an engine with low compression in all 6 cylinders?
The repair depends on what is causing the low compression. Low compression can be caused by a blown head gasket, cracked cylinder head, burnt or damaged valves, worn or cracked piston rings, scored block cylinders. It's kind of hard to imagine that an engine would have low compression on all 6 cylinders unless something major is wrong, or the compression gauge is not measuring properly.
