he can prove it by individually using his geass on any one of them under circumstances where others could see that he isnt abusing his power, but nevertheless using it on them

for example
gather all the people who claimed he used geass on them
have them all wear goggles over their eyes to protect them
and then have each one in turn removes his goggles and Lelouch geasses them to do some small unimportent thing (count till 10) while the others watch (and possibly, kill him if he tries anything bad)

the person who does the counting does not remember for themselves, but the others can confirm that
1)lelouch used his geass on him (which means he couldnt have used it before)
2)Lelouch didnt use his geass to do anything wrong to them
3)Lelouch cant use his geass on them ever again

its simple, and effective, and proves definitively that Lelouch had not used his geass on any of them
it may mean that he wastes his ability to geass them in the future, but he proves to them that he didnt use it on them before, and that they have no reason to fear him using it against them again

the whole point is to prove to the OOBK that he DIDNT geass them before
