How can i copy events to another scene?
you can select several events with shift + click then copy them (ctrl + c) and paste them (ctrl + v) in the event sheet of the other scene.
Generally though if you are going to share events between scenes, instead of copy pasting try external events
What I do is to add all events into a group the just copy/paste the group, but is a better practice to do the @arthuro555 method.
Or maybe create external event and just load in scenes you want.
