1. If you use a green screen, the keys you pull will look aweful. There will probably be a noticeable off-color halo around your subjects, and I would imagine that any quick movement (like that of the drummer) will give you an off-color blur around the parts that are moving, and your audience will easily be able to tell that you used a green screen, and did a poor job of it. Also, it will look dated. We have been in an era of HD for many years now. In fact, we're starting to leave the HD era in favor of a 4K era. Even if you don't use a green screen, and just use masks in your NLE to mask around multiple subjects, and put them all into the same frame, 1) you won't have as much real estate on the screen to work with, because your resolution is lower and you will probably be using a 4:3 aspect ratio instead of a 16:9 aspect ratio, and 2) it will look like you shot it on a camera that is probably 10 years old, or older. Today's cameras give you a much better image to work with.
2. NLE stands for Non-Linear Editor. Basically, it means that you are importing the video files into a program that will show you a preview of the outcome of the adjustments you make to the files in the project that you have created in that program. Then, when you go to render your project from the program, it creates a new video file, building it frame by frame, based on the video files that you've imported into the project and the changes that you've made within the project. In other words, you're not editing the video files themselves; you're editing the project in the program into which the video files have been imported. The outcome is a new video file, but the original video files are untouched.
3. Tutorials are all over the Internet. Do a Google search on pulling a key from a green screen, or on using masks in whatever NLE you decide to use. If you learn better by watching someone else do it, do searches on YouTube.
