I have written about the Knight on a different blog, taking into account the critical view of Terry Jones, and will give the link here (there's a Search button to Knighthood in the Fourteenth Century).

Next come the Squire and the Yeoman, short portraits and worth considering together since both accompany the Knight.
The Squire (a "bacheler", which was a rank in knighthood) is the son of the Knight and represents the younger generation. Whichever moral view you take of the Knight, he was somewhat out-of-date, colourless and shabby whereas the Squire is brightly hued and vibrant. Almost the first word used of him is "lover" and we see instantly from his curly hair (which looks as if it has been pressed) that he is a dandy. Yet he is strong and active.
The next detail, not one of observation, is ambiguous. He had taken part in extra expeditions on horseback and acquitted himself well. These could be sanctioned forages but could also be raids, although they might be seen as chivalrous by a lady. A simile comparing him to a meadow evokes his colourful freshness as he sings and plays the flute all day. He is talented in the social graces: he could compose songs, dance, joust, portray and write. As a lover, he is almost absurdly active, never sleeping. At the end is a sudden, rather unexpected touch to the portrait, a change of angle so that we see a different side to him. Carving at table was an honourable service and part of a Squire's duty, yet there is a humility about the act unseen in him as yet.
Summary and method. This is a portrait of the present generation but individualised as colourful youth, active, talented, dandyish yet robust and hearty, slightly artificial, wholesome and yet artistic. It is the contradictions that make him real and not stereotyped. His exterior, his intricate clothing, is a clue to his vanity by a loose form of metonymy. As always, the description is not schematic: hair, habits, experiences, clothing are apparently jumbled but the juxtaposition can be telling. His strength immediately precedes mention of the horseman's sallies into the countryside.
The Yeoman is the only other companion to the Knight. Chaucer, under his naif persona, accepts the reason given that he preferred it like that. This character is of the outdoors, evoked by the green of his attire and the brown of his face and yet there is brighter colour in the peacock feathers of his arrows. Chaucer seems fascinated by his equipment and accessories, admiring the quality and how well it is all maintained. There is always a positive note in his writing when a man or woman is skilled at their trade and this forester knows his woodcraft in detail and how to care for his arrow feathers.
The Yeoman is not aristocratic but is an open-air countryman, not polished like the Squire. There is no artificiality about him and his pride is in his equipment and expertise, not himself.
Summary and method. Whilst it is an attractive presentation, he does seem very heavily armed for his trade: Terry Jones has argued that he would be in place in the company of a mercenary. I find this less persuasive than his hypothesis about the Knight himself as I do his comment on the Squire's fluting and will not repeat them here. Again, the equipment speaks of his character by metonymy: here is a man fastidious about his tools. He does not droop, but is upright and confident like his quality arrows. Almost all the characters have their own point of vanity but his is not in his person: his close-cropped head contrasts with the Squire's curled locks.
