Ah!

The storyteller's 咦, a flourish that turns the listener's head toward the lamplit room.

The hall was ablaze with silver candles as the blockhead, facing forward, made his bows.

滿堂中, all through the hall, with 中 as zhōng; 朝上, facing forward, with 朝 as cháo; 獃子 with 子 as the light suffix zi. Silver candles blazing, and a pig bowing to an empty chair.

His bows done, he said, "Ma'am, which of the sisters will you match with me?"

拜畢, the bows finished. 那個姐姐, which elder sister, with 那 as nà. He has been married for four seconds and his first question is which one he has married.

His mother-in-law said, "That is just the difficulty: were I to match you with the eldest, I fear the second would resent it; the second, and the third would resent it; the third, and the eldest would resent it — so I remain in doubt, undecided."

這些兒疑難, this bit of a quandary, with 兒 as the suffix; 疑難 is a perplexity. 欲將三女配你 uses the handling-word jiāng. The dilemma is invented on the spot, and it is beautifully shaped: it flatters him by assuming all three want him, and it postpones any answer indefinitely.

Bajie said, "Ma'am, if you fear their quarreling, give them all to me — that would spare the squabbling and the upsetting of house-rules."

既怕相爭, since you fear their quarrelling, takes 相 as xiāng, with each other. 都與我, give them all to me, with 都 as dōu; 省得, to save or avoid, with the light de. He offers it as a service to household harmony.

His mother-in-law said, "The very idea!"

豈有此理, where is there such a principle — outrageous, preposterous. It is still exactly what an indignant Chinese speaker says, and here it is entirely for show.

"You alone would take all three of my daughters? It cannot be!"

一人就占, one man to monopolise, with 一 as yì; 不成, it will not do.

Bajie said, "Listen to what you say, ma'am — who doesn't keep three chambers and four concubines?"

那個沒有, which one hasn't, with 那 as nà. 三房四妾, three chambers and four concubines, is the stock phrase for a rich man's household arrangements. He is not inventing a custom, which is what makes the argument so hard to answer and so grotesque in a monk's mouth.

"Even a few more, and your son-in-law would gladly take them in."

笑納 is the polite formula for accepting a gift — please receive this with a smile — and to this day it is what you write on a card with a present. Bajie applies it to taking wives, in bulk.

"In my young days I once learned an art of hard campaigning; I warrant I could serve each of them to her full content."

學得個, learned a, with the light de. 鏖戰之法 is literally a technique of fierce pitched battle, and it is a leer; 伏侍得他歡喜, serve them to their satisfaction, again with the light de; 一個個, each one in turn. Whatever remained of the monk has now left the room.
