How do I put multiple videos inside one video? Kinda like the movie "24"? - video inside the vergina

I have a record acapella, and I have the video of four part acapella in 4 sections. How can I get more than one video in a video? Just as the film 24 used with the 4 parts of the screen .. What kind of video editing software should I use? Thank you.
