Answer:
That he will be thane the thane of Cawdor
That he will be king
That Banquo's descendants eventually will become royalty
Explanation:
The first and the second tell him:
<em>First Witch
</em>
<em>All hail, Macbeth, hail to thee, thane of Glamis</em>
<em>Second Witch
</em>
<em>All hail, Macbeth, hail to thee, thane of Cawdor!
</em>
Macbeth was already Thane of Glamis, but the Thane of Cawdor was someone else.
But the third says something different:
<em>Third Witch
</em>
<em>All hail, Macbeth, thou shalt be king hereafter!" </em>

About Banquo, they say:
<em />
<em>Third Witch
</em>
<em>Thou shalt get kings, though thou be none:
</em>
<em>So all hail, Macbeth and Banquo!</em>
