When shall we three meet again In thunder, lightning, or in rain?
That will be ere the set of sun.
When the hurlyburly's done, When the battle's lost and won.
Fair is foul, and foul is fair
No more that thane of Cawdor shall deceive Our bosom interest: go pronounce his present death, And with his former title greet Macbeth
O valiant cousin! worthy gentleman!
They smack of honour both. Great happiness!
Looks like showing that they know everything. It indicates the characters as some sort of narrator of the story who talks how the act goes. Every word they use is the word which has a negative and dark image. It creates their dark-sided character and helps create the dark and suspicious mood of the act.
Look what I have. Here I have a pilot's thumb, Wreck'd as homeward he did come.
But in a sieve I'll thither sail, And, like a rat without a tail, I'll do, I'll do, and I'll do.

Speak, if you can: What are you?

Praising sergeant even too much shows he is a warm, generous and benevolent person. When he adds "great" to Macbeth's name it shows he values his people.

Would they had stay'd!
Their conversation makes a point on savagery and cruelty they have, and shows how their point of view differ from humans. The sentence "I'll do, I'll do, and I'll do" shows her vindictive personality.
And I another.
Macbeth: Showing his attitude which commands to people around him. Asking so many questions which indicates his hidden fear to unknown or big victory. Banquo: Short and concise line shows his confidence and stability. What he said when he saw the witches for the first time indicates the susceptive and cautious personality he has. The line "[I] neither [...] your hate" shows his braveness. →
What are these So wither'd and so wild in their attire, That look not like the inhabitants o' the earth, And yet are on't? Live you? or are you aught That man may question?
→This scene shows Macbeth and Banquo's personality in contrast. Macbeth believes what witches said and shows his fear for the witches(indicates unknown/big change/victory) while Banquo is suspecting its reliance.
Were such things here as we do speak about? Or have we eaten on the insane root That takes the reason prisoner?
