The first pair, fourth pair, and fifth pair can be used to contrast the careers of writers and editors.
(this goes for the picture u have put in. if you need me to choose from the text you listed i can also do that) Hope that helped, if you don't understand, you can comment below and i'll edit it.
In my opinion, the whole poem is quite ironic - although she is mentioning the exultation and the royal color of death, the poem itself begins with the narrator saying that she cannot breathe - that she doesn't want to die.
So, I would say that the ironic parts are:
Exultation is the going
Of an inland soul to sea, -
Past the houses, past the headlands,
<span>Into deep eternity!</span>
