About the plot of the movie Inception

I didn't really understand the movie Inception. There were mainly the following questions:
1. Wasn't the mission supposed to implant an idea into the young Fischer so that he could destroy his father's empire and prevent his father's company from becoming a global monopoly that would leave Saito without a place to live? Then why did Fischer realize that his father wanted and trusted him to be his heir, and the mission was completed?
2. What was the meaning of the fourth dream? What was the meaning of the conversation between Cobb and his wife?
3. Didn't they kill him in the third layer? Why did they revive him in the fourth layer?
4. Didn't you say that due to the complexity of the multi-layered dream world, the original principle of death leading to exit from the dream world would be invalid? The person who was killed in the dream world would enter a state of wandering. In this state, even if the real world was only a short moment, the dream would feel like decades. Moreover, this person would not be able to distinguish his dream world from the real world. Then why did Cobb and Fischer jump off the building in the fourth layer of the dream world and return to the third layer? Also, when everyone returned to the first layer of the dream, since they couldn't commit suicide to return to reality, how did they return to reality?
5. Weren't Cobb and Saito stuck in the free space? How did they return to reality?
6. What does the ending and the opening mean? (Cobb is sitting in front of a very old Saito, who tells him that they have to escape back to the real world. Saito picked up his gun and tried to commit suicide.

The movie Inception told the story of a mysterious world made up of dreams, which was starred by Leonardo DiCaprio and Tom Hardy. In order to complete a mission, the protagonist team had to travel through multiple dreams and try to obtain useful information from each dream.

The protagonist of the story was a psychologist named Alan West. He and his assistant, Cristoff de Vito, decided to use their advanced technology to help people enter a deeper level of dreams and complete an unprecedented task.

They first entered a dreamland called the " Multi-Layered Dreamland ". This dreamland had a complex structure and different rooms. Allen and Cristoff de Vito used their technology to successfully enter a room called the Dream Shuttle, which allowed them to travel between different dreams.

They began their mission and entered a dream called the " subconscious." In this dream, they discovered an important piece of information that could help people realize their wishes. They decided to use this information and continue with their mission.

They continued to travel through different dreams and complete missions. In the process, they encountered many difficulties and challenges, including monsters in the dream and mysterious organizations. But Allen and Cristoff de Vito used their skills to overcome these difficulties and complete their mission.

In the end, they reached their goal and returned to the real world. In the process, they not only completed an unprecedented mission, but also learned how to face the deepest fears and challenges in their hearts.
