Strictly speaking, it is in act 1 scene 1 where the witches say "Upon the heath/ There to meet with Macbeth."From this we know that Macbeth is on a heath. It's not much information but it is the first we get.
Young Siward is the first to fight Macbeth in Act V. Macbeth kills young Siward.
In Act 1 Scene 7 of Macbeth, when Macbeth is alone and speaking his thoughts out loud, this is called a soliloquy. It is a dramatic device used to reveal a character's innermost thoughts and feelings to the audience.
The name Macbeth first was used in Act 1 Scene 1 of the Shakespearean play 'Macbeth'. The three witches were gathered together on the open heath. They were deciding where their next meeting would be. The second witch settled on the heath. The third witch explained that the heath was where they all would be able to meet with Macbeth [Line 7].
First Witch. Second Witch. Third Witch. In the First Folio Act 1 Scene 1 and Act 4 Scene 1 they are identified as 1, 2, and 3. There is also a head witch called Hecate and three other witches who are usually written out of any performing script because 1) they are silly and stupid and 2) they were added to Shakespeare's play later, probably by Thomas Middleton.
The First Witch seeks revenge on the woman because the woman's husband refused to give the First Witch a chestnut. This encounter sets a tone of malevolence and foreshadows the themes of revenge and supernatural elements that will be prevalent throughout the play.
Act I Scene III is when Macbeth first meets the witches. HOWEVER this could be different for different copies of the play as they are all different.

This is from the lines of the second witch in Act IV, scene one of Macbeth.
The first apparition in Shakespeare's Macbeth is a floating head that tells Macbeth to beware of Macduff. It says that Macbeth should be on guard against Macduff because he poses a threat to Macbeth's reign.
The witches never said "Macbeth, Macbeth, Macbeth". In Act 4, Scene 1, both the First Apparition and the Second Apparition begin their prophecies by calling out, "Macbeth! Macbeth! Macbeth!" Macbeth responds to the First Apparition by thanking it for warning him against the Thane of Fife (Macduff). Macbeth responds to the Second Apparition with: "Had I three ears, I'd hear thee."
Macbeth comes. (ACT 4, scene 1, line 48)
