the porter
A porter is simply the man who is in charge of the gate. He's the one that opens it and closes it, and makes sure people who aren't supposed to come in don't. The porter from Macbeth, specifically, is the comic relief after Duncan is murdered. Shakespeare knew that he had to keep people interested, and thus needed to put in something funny. The porter has been drinking all night, and when he hears Macduff and Lennox knocking, he imagines that he is porter to the gates of Hell. He then proceeds to imagine what kind of people he would let in. I hope this helps.

the porter
In Shakespeare's "Macbeth," the porter imagines himself admitting three types of transgressors to hell: a farmer who hanged himself due to poor harvests, a equivocator who deceived others with false promises, and a tailor who stole from his customers.

The porter's musings serve to underscore the chaotic moral landscape in which Macbeth and Lady Macbeth operate.
