Hi @BoHyun Jung 

current means the record on which your email is getting triggered, through this current object you can get the values of the columns of that record.

template means if you want to add any message through email script into the body then you need to use template.print("your message");

Email means if you want to add any optional email apart form the mail id which you've configured like setBody etc.,

Email Action means GlideRecordObject  for the email notification

Event means the GlideRecord object of the event.
