"y friend said, it is really impossible to get back those sites ranking which where hit in panda update period... Is that true? "
imo it depends what the issue with the sites were/are? I reckon if you posted your website...within 30 seconds of looking at it some will be able to tell you why you were hit. It usually is that obvious.
