Yale and Georgetown are in reach - you have a reasonable shot at both of them. Wharton/Lauder is a stretch (nothing wrong with you - it's just that you're up against a lot of other blue chip folks who are also competing for limited spots), but you have enough of an outside shot that it's worth at least giving it a go.
If you're looking to get into *a* school next year, you should apply to a few more. When it comes to b-school admissions, it is ultimately a numbers game. In other words, you should apply to 4-6 schools total to yield roughly 1-2 acceptances. Anything less than 4 schools and you're taking a bit of a gamble. What works best for many applicants is this:
1-2 stretch schools
2-4 sweet spot schools
0-1 safety schools
