Location of some characters (Very important)

I was wondering when do you get these characters:
1.Zoo
2.Jezzie
3.Batabog
4.Nash
5.Luba
6.Rosa

And how do I get the rock out of the way.

1 you get him temporaraly as a underking mission then you get him on day 13 hes located on the little opening in the mountains east of meterolia

2 if you saved her in lp 1 and imported she arrives about day 12 if not you must do the witches quest and get her revived you must have zoo speak to the ghost in crypt of 7000 skulls on day 13 and get him to make holy water which shall take one day and on day 14 give the holy water to the ghost to get the book of evil give the witch it and she will revive jezzie
