I would not be surprised for you to be accepted to any of these colleges. But, your chances are slim for almost all of these because they are receiving far more highly qualified applicants than they can take (several times more). I think that GW is likely and though your odds are better at BC, BU, and Michigan than at the rest of your list, I would not call those likely, either.
If you apply ED anywhere it should be at your clear top choice school. Additionally, it should only be after your family runs the Net Price Calculator and finds that the price is what they are willing and able to pay for every year for four years.
I’m also very curious about your rationale for how you selected the schools on your list. Explaining might help provide clarity on what’s important to you, particularly if anyone were to suggest additional options for consideration.
There are a couple of resources that I am going to link that you may have already read, but might prove helpful:
Comments about choosing a school for undergraduate study from The Philosophical Gourmet, a site that ranks graduate philosophy programs.
A column discussing where students at top doctoral programs in philosophy attended undergrad. The lists of various colleges here might be a good springboard for thinking about possibilities.
A ranking of graduate programs in philosophy
@merc81 already linked to the site for undergrad philosophy programs that I would have linked.
-Also, don’t forget about honors programs at big state schools (Rutgers, Pitt, several UCs, etc).
-Brandeis and Tufts are a couple of schools you might want to consider where your odds are a bit better, especially as you seem to like the Boston area.
