The short answer would probably be the proverbial "It depends." For illustration, 7 instances of something could be both some and many, or it could only be some and not many, depending upon the greater context. Is it 7 out of 8? Then it's probably both some and many. Is it 7 out of 1000? Then it is probably some and not many.
But if this is in terms of a contract, determining the "legal meaning" might be resolved by the general rule that ambiguous contract terms are interpreted against the drafter.
