How do I add more than one npc to an event?

So the event is the opening cutscene but I need to put 6 npcs in it, can I put them all in one event or do I have to make separate events for them?

Each NPC will be it’s own event to display the graphic. But it is best practice to have one event controlling all the others.

Use a master event to control the move routes and dialogs of the events that display the NPC’s graphic.

There's a nice article about the dynamic between events and npcs on the blog, particularly for this topic. The main take away is that a npc is a character in a game which is represented by a graphic; the graphic's event and the event that control it or make it appear don't necessarily have to be the one and the same. http://blog.rpgmakerweb.com/tips-and-tricks/events-arent-npcs/
