Why don't you read the book and find out? They go to Castle Rock which is the only place that Jack admits that he has never been to during his hunting expeditions. When no beast is found they then decide to look on the mountain top, which is where Samneric reported they had seen it.
Lord of the Flies documents the progression of "innocent" boys into savagery.
Percival says that the beast comes from the sea. To help the whole situation, at this point the boys see a shark out in the water. Maurice pipes up that his dad said there are still unknown creatures in the sea. Then Maurice unhelpfully adds that it could be a squid. All the boys start arguing about whether a squid can come on land or not until Ralph silences everyone.
When Jack and his tribe kill the pig they stick the pigs head on a spear and put it in the clearing as an offering to "the beast". They do not know that the beast is actually a part of them and not a physical being.
Yes he was. He had just found out that the beast lives within and was going to tell all the boys. But the boys were having a feast and partying. When he comes out of the jungle, the boys think he is the beast and stab him to death, everyone takes part. The next day everyone realizes it is Simon; yet no one will admit it was. :)
The signal fire went out when Jack made Samneric leave the fire duty to go hunting. It also goes out when Samneric "see the beast".
The "beast" that Samneric see in "Lord of the Flies" is actually a dead parachutist whose body gets tangled in the trees and moves with the wind, creating the illusion of a monster. The boys mistake the parachutist for a frightening beast and report it as such to the rest of the group.
Lord of the Flies documents the progression of "innocent" boys into savagery.
The boys react to the idea of the beast in various ways. Some, like Simon, see it as a metaphor for the darkness within themselves and in humanity. Others, like Jack, use the fear of the beast to control and manipulate the other boys. Ultimately, the existence of the beast becomes a manifestation of the boys' inner savagery and descent into primal instincts.

It really depends on which part of the book your referring to, but i believe it is the beast that is up there or what they assume to be the beast.
The boys see a looming storm on the horizon in "Lord of the Flies," which adds to the growing atmosphere of fear and uncertainty on the island. It signifies the increasing chaos and conflict among the boys as they struggle to maintain order and civilization.
The boys respond with excitement and a sense of adventure at the possibility of rescue when they see smoke in the distance in "Lord of the Flies." They believe it could be a signal fire lit by adults searching for them and rush to investigate.
Ralph, Jack, and Simon
I assume that you are referring to the three boys who climbed to the top of the mountain in chapter 7: Shadows and Tall Trees. The three boys were Ralph, Jack and Roger. They saw exactly the same thing that Samneric had earlier seen, the dead body of an airman still attached to his parachute. Just like Samneric, in the fading light of evening, they mistook the body, which moved as the wind caught its parachute, for the beast.
Early in the novel Ralph, Jack and Simon climb the mountain to ascertain if they are actually on an island. Later in the book Ralph, Jack and Roger climb the mountain in search of the beast.
From the book, "The Lord of the Flies", Simon pictures the new beast as the evil that is inside of everyone. He sees this human as once heroic and sick.
