1) Jupiah is Arthur's father. The three kids are sent back by Borgin from a point in the timeline that's farther ahead from the Future that the player sees. An NPC even states that "Borgin came from a farther future of doom" or some such. However, Jupiah is just a brain for much of the game, so he'd have to be reconstituted at some point in order to have a kid before the game begins. This would have had to occur before the First Party left for Pureland in the Talon2, whereupon Jupiah is killed and his brain is put in the ship's computer/powersource/whatever. I suppose this does create some sort of time loop, but then Arthur & Co wouldn't have been sent back in the first place since once the Entity is destroyed, it vanishes from all 3 time periods (as implied in the ending). So it's kind of iffy.
2) It would seem that the Water Entity does indeed pour out directly from Pureland's ocean, hence the "hole" in that world that leads out through the Entity as seen in the ending sequence.
3) I'm 99.999% positive that the "Four Fiends" of this game are Dogra, Ashura, Chaos, and Maitreya.
This is my signature until I can think of a better one.
