Homophones are those groups of words sharing the same pronunciation albeit they have different meanings and spelling; and when heard, it's the context what allows to identify the corret meaning, so in the 1st one, since we talk about sandwiches for a couple, two = 2

the 3rd one is a question about "who" and "what", thereby the contraction "they're",

and the last one is a statement about ownership, thus the possesive case of the pronoun they which is "their".
