A bit late, but here's the answer for anyone still on this question:
Information for only the audience - Dramatic Irony
(Dramatic irony is a form of irony that is expressed through a work’s structure: an audience’s awareness of the situation)
the text of a play that the director and actors follow - Script
(We can look at these like "Jack - But why?". These aren't instructions on when to appear; those are stage directions)
A conversation between two or more characters - Dialogue
(Dialogue is defined as "Conversation between two or more people as a feature of a book, play, or movie")
Instructions, usually in italics, to an actor or director - Stage Directions
(We can look at these like "Main character appears on stage")

The terms such as script, dialogue, dramatic irony, stage directions, etc. are all words that are associated with a performance such as a play. All these elements such as the script and dialogues are performed by the actors to make the play a success.
