Yes, arrow bags usually had 24 arrows, but archers had between 71 and 88 arrows. They had to bring 23-40 arrows to the muster. The rest, 48 arrows, or two sheafs, were supplied by the crown.
At least 40 arrows.
James Skidmore in 1440 was to serve with:
"... as a man at arms with vj. [6] archers in his company, all on horsbak and wele chosen men, and likely personnes wele and suffisantly armed, horsed and arrayed ev'ry man after his degree; that is to say, that the seid James Skidmore have hernis his degree; that is to say that the seid James Skidmore have hernis complete wt basnet or salade, with viser, spere, axe, swerd, and dagger; And all the seid archers specially to have good jakks of defence, salades, swerds and sheves of xl.

30 arrows.
The Abbeville ordinance: 31 July 1471
"The three mounted archers must each equip themselves with 30 arrows, a bow, a two-handed sword and a dagger."
30, or at least 23 arrows.
The Statutes and Ordinances of War issued at Calais, 1513
"every archer had his bow and arrows whole; that is to wit, in arrows 30, or 23 headed and whole in sheaf at the least"
24 arrows.
Henry Barrett, a member of the Yeoman of the Guard writing a marching order diagram in 1550.
"... a sheaf of arrows in number xxiv [24] whereof I whish viii [8] of them more flighter then the rest to gall and annoy the enimyes farter of then the usuall custom of the sheafe arrowes, whose sharp hallshot (hail-shot) may not be indured, neither may th'enimyes putt up hande or face to incounter the same"
24 arrows.
Sir John Smythe writing in 1590.
"every man one sheaf of arrows, with a case of leather, defensible against the rain... whereof eight [arrows] should be lighter ... to gall or astonish the enemy before they shall come within the danger of ... harquebuss shot."
Here from Clifford J. Rogers' article: The Battle of Agincourt.
"At Poitiers, according to the Eulogium historiarum, some archers loosed over a hundred shafts before the battle was decided, however, Geoffrey le Baker indicates that in order to do this they had to recover arrows from the ground and from the bodies of “half-dead wretches” during a pause in the fighting."
