I am looking for one or more conflicts from each of the acts of Macbeth.
Well, you are right in indicating that there are a number of conflicts in this brilliant play. You might like to consider the following:
In scene 7 of Act I, Macbeth's brilliant soliloquy is a perfect example of internal conflict, as he debates within himself whether or not to kill Duncan and the possible consequences of such an action. This is a very important soliloquy in the play and is worthy of much attention.
In Act II scene 2, consider the conflict between Lady Macbeth and Macbeth as she berates him for his infirmity as he finds himself unable to go back into the room and smear the grooms with Duncan's blood. She is very angry with him, saying "Infirm of purpose!"
In Act III scene 4, think of how Macbeth is shown to be struggling with the external manifestation of his conscience, as at the banquet he sees the ghost of Banquo sitting. This of course clearly indicates the extent to which he is battling within himself both for his sanity and goodness.
In Act IV, scene 1, Macbeth is presented as being in conflict with the witches as he demands answers to the riddles they present him with. He is frustrated at not getting the clear answers that he seeks and is left with more questions than answers.
Finally in Act V, the obvious conflict is the armed battle between the forces of Malcolm and what is left of Macbeth's forces as Malcolm's army sweeps upon Macbeth's castle, and Macbeth and Macduff face each other in armed conflict.
