Hi there,
Assuming your apps are done and ready to submit if we're talking R2!

But yes I think your school list is reasonable; still a bit challenging but reasonable.
Again essays are probably already written and things are ready to go, so perhaps less value in giving too much advice at this point, but in general I'd say elements you need to convey in your application for best chances include:
-what past experiences and skills will benefit you in the classroom, and later in your career
-what key traits and experiences make you UNIQUE; basically, 'why YOU??' vs other applicants
-why you want the MBA, with clear short term and long term post-MBA goals
-why NOW
-why that specific school is right for you
If you lack any of the above components, you risk that another well or similarly-qualified applicant who includes all of those, will wind up getting accepted over you!
Good luck and keep us posted !!
