Macbeth's cockiness in Act 5, Scene 3 is a result of his overconfidence stemming from the witches' prophecies. He believes in his invincibility due to the ambiguous nature of the prophecies, particularly the one about "none of woman born" being able to harm him. This false sense of security leads him to underestimate the threat posed by Macduff, ultimately contributing to his downfall.
In scene 3 of Macbeth, the Porter/doorman is drunk. They have been up drinking until three in the morning.
This must be Act I scene 4 that we are talking about. The king has just announced that the party is at Macbeth's place, and so everyone is headed to Inverness.

She pushes MacBeth to kill the king and by doing so fulfills the witches predictions.
foreshadowing it forshadows the madness of both MacBeth and his wife.

Macbeth is the one who dismisses Banquo after that conversation, saying "Hie you to horse. Adieu, / Till your return at night." If you mean the guests at the dinner party in Act 3, Scene 4 (after Banquo has been murdered and is appearing at the dinner as a ghost), Lady Macbeth dismisses them by saying "At once, good night. / Stand not upon the order of your going, / But go at once."
In Act 3, Scene 2 Lady MacBeth explains how her desire has been satisfied but she is not happy. She says "nought's had, all's spent" meaning she has nothing and has spent everything. MacBeth comes in explaining how the entire affair is not yet done and how he regrets it, is scared, and has been having nightmares.

That Banquo will figure out that Macbeth killed Duncan by knowing that Macbeth would take the prophecies of the witches seriously and carry out the murder which would make part of the prophecies come true.
The page number differs according to the particular version. A more effective and more exact way of locating the royal murder is the identification of the specific act, scene and line number. The closest that one may get to the murder is Act 2 Scene 2 Line 14. That's the passage in which Macbeth tells his wife that the foul deed in fact is done.
