Hi. Essentially because they formed in different conditions and have different masses.

I liked Zerobyte's answer--like dipping into a bowl of chili.
However, if I were to have some chili, hot peppers, some garbanzo beans, along with boiled cabbage, I can actually create my VERY OWN atmosphere! (That is, a very different atmosphere from where I started, especially if it is created in a very small space such as a car, a shower, or a cubicle)!

It's kind of like taking a dip from a big pot of chili. Some ladlefulls will have more beans than others, some will have more hot peppers, etc....
The stellar disc that formed our solar system wasn't homogenous, and whatever was there at each region ended up forming the clumps we know as planets.

Formation determines what gases are available for the atmosphere, mass determines the escape velocity (how much gas can be naturally lost to interplanetary space) and location in the solar system determines temperature which affects both escape velocity and the chemical composition of the atmosphere.

first of all, nothing is the exactly the same in any way shape or form...planets have different sizes and shapes therefore it has different features
