1.a) Ralph [Stan Marsh
1b) I picked Stan to be Ralph because on the adventures of life that often encounter him and his friends he is almost always the first to take the leadership role. Gets along great with everyone, except Eric Cartman which is one of his good friends..even though he really hates him. Just as Jack and Ralph can not really coexist with one another, but still manage to not kill each other, sorta.When it comes to Stan and Butters (Ralph and Piggy) they are some what on good terms being atleast decent human beings although even Stan is quick to get annoyed by Butters. When it somes to the "Beast" (Al Gore/ManBearPig) Stan simply believes its dumb and pointless. 
2.a) Jack [Eric Cartman]
2b) Eric Cartman is not an everyday normal child. The only normal thing about him seems to be that he is 9 years old and a 4th grader. Other than that he is anything but ordinary and not in a good way. He was raised by a single mother and abandoned by father after being concieved. Cartman reminds me of Jack in that both are complete sick, twisted, maniacal, savages. Cartman how ever takes it to an extreme level going so far as to plot whole conspiracies to get even with someone. Although he does hang out with a group of friends in reality none of them like him what so ever. He especially has hatred towards Butters and Kenny. Just as Jack has something against Piggy. Cartman is always picking on Kenny due to Kenny being subject to poverty. As is the situation with Jack and Piggy with a different scenario as is Piggy not being as fit as the rest of the boys. If they were all in the same situation i KNOW Eric Cartman would resort to the same measures as Jack and his Hunters if not worse. (i.e. cannabalism, torture, ect.)3.a) Piggy [Butters Stotch]
3b) I picked Butters to be Piggy for several reasons..like he hangs around with the group of boys, at times...when they will let him. He is often the huge subject of teasing, bullying, and humiliation. He gets along ok with some boys, just as long as he stays quiet. I think he would play Piggy well because they share many traits such as not being as popular with all they boys as they might hope to be, being a well rounded good natured boy, and having to resort to recieving pitty at times. If not scared or confused he is often being picked on and ridiculed by pretty much everyone even people that may act friendly towards him at times. Very much the same as Piggy and Ralph.4.a) Simon [Kenny McCormick]
4b) I picked Kenny to play the role of Simon simply because he is always dying. At times being killed horribly such as Simon. He may also fall pray to something of false nature such as hallucinations. He is good friends with Stan and on not so much good terms with Cartman. I feel as if no one could play Simon better, as this role was made for Kenny for the simple fact that he has been killed about 79 times in the series of South Park.5.a) Roger [Damien]
5b) I picked Damien to be Roger for one main reason. He is the son of Lucifer and is the one boy most likely to kill someone. The way Roger killed Piggy i think he'd have to atleast compare to Damien. Damien is also the only character i nthe series to use his powers to change someone (Kenny) into a duck billed platupus.
Another reason i would cast Damien as Roger in my LoTF is because he is simply just as unlikeable as the real Roger.
6.a) Beast [Al Gore/ManBearPig]
7.a) They are stuck on a bus about to go over the edge of a cliff
7b) Things I would change..
1. They are stuck on a bus and they can not leave or it will tip over.
2. They are not fighting over specs but cheesy poofs
3. Instead of a shell, the puppet, Mr Hat takes the role of the conch
8.) I would atleast change the title to
South Park Lord of the Flies, simply to credit
the source of my story and my cast.
