I'm trying to find the name (type) of music that is played in this video starting at minute 02:20. It's very majestic. It's not orchestral music right? Cause I'm looking for songs that are similar and cannot find a keyword on Google to search for it.
As @PiedPiper mentioned, the name of this genre is epic or epic soundtrack.
It's typically written for feature films and big-budget video games. Since it usually requires an orchestra, it can be expensive to produce (unless the orchestra is simulated) which is why it is generally associated with larger projects.
A search for "epic music" on Google will bring you relevant results.
