Hey! Looks relatively similar to programs that I'm shooting for. I've done way too much research into the academic profiles/statistics so maybe I can help with your assessment. How is your quantitative background/experience-- anything to combat the Q score? Is your relevant coursework GPA closer to 3.5/higher? Is your undergrad institution top-tier or well-known for its rigor?
Your verbal GRE will make up for the Q score in some of these programs (but not sure if Fordham will be more strict since their program is relatively Q-heavy). You do have a higher verbal than Fordham's average verbal though, so that's a plus. Because of this, I assume also that your SOP must be well-written, which will give you some points.
I also wonder about the programs you chose (I applied to a couple of those, but a different one at American). I wonder because you applied for Development Practice at Emory, but at American did you consider their Development Management program (which is very similar to MDP)? Also, I don't know a lot about Notre Dame's MGA, but is that more related to international affairs than development- or is it that there is a development option? What are your career goals/what did you explain were your career goals in your SOPs?
Peace Corps service is definitely a big plus, so that will give you some bonus points. What sector did you serve in?
Your language profile makes me presume you were in Malawi, or maybe Zambia? PC service in Africa is very well regarded amongst grad programs in the development field (I know that Fordham, for example, very much appreciates PCVs of Africa)
