If bene gesserit mothers were unable to unlock generic memory of their male predecessors, how Alia can possibly be possessed by Baron Harkonnen?
Is Alia kwisatz haderach then?
How is this possible, if kwisatz haderach suppose to be male?

The primary goal of the Bene Gesserit breeding program was to create a male that was capable of accessing both the female memories and those that were barred to them, found in the "place that they can't go" (e.g. male source memories) giving them full access to both the past and reliable visions of the future.
That is the place where we cannot look, she thought. There is the place the Reverend Mothers are so reluctant to mention–the place where only a Kwisatz Haderach may look.
Alia is born capable of accessing those memories (as evidenced by her possession by the Baron Harkonnen), but it's certainly arguable that the Bene Gesserit didn't actually know what they were going to get with the Kwisatz Harderach, not just a male Bene Gesserit but also a powerful being capable of twisting the timelines to their own advantage, something that Alia never really mastered due to her gender and personal weaknesses.
“Try your tricks on me, old witch,” Paul said. “Where’s your gom jabbar? Try looking into that place where you dare not look! You’ll find me there staring out at you!”
Note that Leto II and Ghanima also had this ability but, again, neither really fit the mantle of the Kwisatz Haderach since they're both born with this ability rather than gaining it through the spice trance.
The Kwisatz Haderach was the culmination of a 10,000 years long Bene Gesserit breeding programme. Their goal to make a male capable of being essentially a male Bene Gesserit and thus able to see the Male ancestral side memories. It was a name for a Unique individual.
Alia, Leto II, and others, preborn/not who also had this ability, let the term evolve passed a unique individual, but into a term that applied to anyone with male ancestral memories. Paul was the true Kwisatz Haderach due to the precise breeding program, and was the end goal of the project.
