imho, the problem with your current approach is, that SVM1 does not know person 3 as a negative, though it should.
try to train SVM1 with features from class1 as positives, and features from all other classes as negatives. (all labeled -1 , irrespective of their real id, here they are just 'the negatives')

try to train SVM1 with features from class1 as positives, and features from all other classes as negatives. (all labeled -1 , irrespective of their real id, here they are just 'the negatives')
last but not least, if your features are long enough, consider using one multi-class svm, too.
