My judgments assessments of your brothers are as follows:

Lior: Parents adore him, even if he might have run into their cat with his broom. Would plan a bachelor party at one of those paint-your-own-pottery places.
Lavi: A fun time. Able to fool elders into thinking he's a responsible young man.
Leib: A fun time, sometimes too fun. Parents hope this is just a phase.

How'd I do?
