after the attack on Schaffen on May 10 only three Hurricanes were left: H-23 and H-34 flew to Beauvechain, followed later that day by the repaired H-29. In two attacks on May 11 all three were damaged, two completely, one damaged. That latter one was finally destroyed by Belgian personnel upon the transfer to Belsele on the evening of May 11.
The H-36 was not yet fully assembled at the Etablissements Aeronautique at Evere and transported to Bordeaux by train. This makes me suspect the H-37 and 38 were not yet delivered and in even less usuable state.
H-25 had nosed over on December 1 and probably still in repair,
H-26, -33 and -35 were damaged on March 2 and probably still in repair on May 10 since not listed on any operational list. The H-39 was written off per the same date.
h-28 was written off on Feb 28 after a landing crash.
I have one statement saying that on May 10 there were not 11 but 12 Hurricanes operational, with the H-41 standing separate from the rest.

Overall this leaves as unconfirmed the H-24, 37 and 38, and a question mark for the 41. Other than that all 23 from H-20 to H-42 are accounted for.
