Blazon: Bendy of eight or and azure a label* gules
No, no, almost certainly not THOSE Montforts. Given the differencing, I’m almost certain that Robert is either the son or younger brother of Peter/Piers de Montfort. Given the dates, it’s probably two brothers; Peter de Montfort Sr. died in 1265, but both sons would have been at least in their twenties or thirties when the roll was composed. Just to confuse matters, Peter Sr. did fight in support of Simon de Montfort (note the differing arms) before they both died at Evesham. Peter Jr. eventually secured a pardon for their father’s actions in 1267.
*The depiction in the original roll is degraded enough that I’m not quite sure how many points are intended. It seems to be at least three, but five is possible.
Blazon: Gules a cross argent, a label of three points azure
This is actually pretty straightforward, as Italian arms go. Gules a cross argent are the arms of the house of Savoy; in 1424, Duke Amadeus VIII of Savoy granted his oldest living son (also named Amadeus, because of course) the title Prince of Piedmont. And, as the eldest son, Amadeus bore the arms of his father with the traditional label for difference. There have been slightly different configurations of the arms over the years (mostly adding, removing, and changing the tincture of bordures), but the cross and label have remained consistent.
From Encyclopedia of Heraldry by John Burke and John Bernard Burke (1844)
The label is a very common mark of cadency, often used in English heraldry. Most of the time, it signifies the arms of a first son while his father is alive; once the father dies and the first son inherits, the label is removed from the arms and the son bears them undifferenced. The label then passes to the first son of the first son, and so on. However, because there are always exceptions for the royal family, anyone who bears the royal arms of the United Kingdom who isn’t the current sovereign always gets a label – typically argent, typically of three points. Anyone who isn’t the heir to the throne will have something put on their label to signify that they’re not the heir, just in the line of succession. Below) are the labels of some of the royal family in 1842.
Princess Victoria Adelaide Mary Louisa, daughter of Queen Victoria and Prince Albert, later German Empress and Queen of Prussia : a label argent charged with a rose between two crosses gules
Ernest Augustus, King of Hanover and Duke of Cumberland, fifth son of George III (i.e. Victoria’s uncle) (1771-1851): a label argent charged with a fleur-de-lis azure between two crosses gules
Prince Augustus Frederick, Duke of Sussex, sixth son of George III: a label argent charged with two hearts in pale between as many crosses gules
Princess Mary, Duchess of Gloucester and Edinburgh, fourth daughter of George III (1776-1857): a label argent charged with a rose between two cantons gules
Princess Sophia, fifth daughter of George III (1777-1848): a label argent charged with a heart between two roses gules
Princess Sophia Matilda of Gloucester, first daughter of Prince William Henry (i.e. Victoria’s cousin) (1773-1844): a label of five points argent charged with a fleur-de-lis azure between four crosses gules
Arms of John de Lacy, Earl of Lincoln 1232-1240 (c. 1192-1240) and Margaret de Quincy, Countess of Lincoln 1232-1266, suo jure 1240-1266 (c. 1206-1266)
From p114 of Lacies Nobilitie by Sir John Ferne (1586)
Blazon: Per pale baron and femme I per quarterly i and iv per quarterly or and gules a bend sable and a label of three points argent (Lacy), ii and iii or a lion rampant purpre (Nigold/Neale), II per quarterly i gules seven mascles conjoined or 3, 3, and 1 (Quincy), ii per pale azure three garbs or (Chester) and azure a wolf’s head erased argent (d’Avranches), iii gules a cinquefoil ermine (Beaumont), iv gules a pale or (Grandmesnil)
You may recognize the baron’s arms as those of Roger de Lacy, Baron of Halton and Pontefract; John was his eldest son. They were jointly created Countess and Earl of Lincoln in 1232. The grant was mostly due to Margaret, as the title had previously been held by her mother Hawise of Chester. Thus, John was only Earl of Lincoln by right of his wife, and when he died in 1240, she retained her title in her own right.
Blazon: Per quarterly I and IV argent on a cross azure five crescents or (Piccolomini); II and III paly of four i or four palets gules (Aragon), ii barry of eight gules and argent (Hungary ancien), iii azure semé de lis or, a label of four points gules (Anjou ancien), iv argent a cross paté between four crosses or (Jerusalem)
Ottavio inherited the quarters of Aragon, Hungary ancien, Anjou ancien, and Jerusalem from his ancestor Antonio Piccolomini d’Aragona, who married Maria d’Aragona, the illegitimate daughter of Ferdinand I of Naples. Many representations have Ferdinand’s arms in the first and third quarters, as Maria’s lineage was (though illegitimate) more noble than Antonio’s.
Arms of John de Lacy, Earl of Lincoln 1232-1240 (c. 1192-1240) and Margaret de Quincy, Countess of Lincoln 1240-1266 (c. 1206-1266)

Blazon: Per pale baron and femme or and gules a bend sable and a label of three points argent (Lacy) and gules seven mascles conjoined or 3, 3, and 1
The title to the earldom of Lincoln was carried through Margaret’s side, inherited from her mother, Hawise of Chester, who inherited the title from her brother Ranulf de Blondeville. As Margaret was the one with the initial right to the title, it returned to her in her own right after John died.

Roger received the castle and barony of Pontefract through Albreda de Lisours. (Ferne has her as Roger’s mother, but other sources point to her as his grandmother; I am not sure of their exact relationship.) He was not born a Lacy; his father, John fitz Richard, was the baron of Halton and grandson of Nigel de Cotentin. Roger assumed the Lacy name and arms as a condition of his succession to the properties of Pontefract.
