Honestly if I were to look at your GPA alone I would say not that good. A 3.1 just isn't really that competitive for most schools
in general, and I see you applied to some highly competitive ones. The minimum is usually around a 3.0 but you may go up against people with 3.5's -4.0's.
How does your pre-req GPA look itself? Do those schools look at pre-req GPA and overall GPA separately? (I know a lot of ASBN programs do.)
If so this may help you if you did really well in your pre-reqs needed for nursing.
Your other stuff, as far as experience sounds good. Did you put any of that in your essay to kind of explain your GPA? If so they may take this into consideration. With some schools it's strictly about GPA, with others they look at everything, including experience and circumstances.
All you can do now is hope for the best. I'm a firm believer in at least trying, the worse that can happen is they say no.
No one can definitively say what your chances are for being accepted because you never know what the application pool looks like for the year you apply. One year you may get a pool where many applicants have GPA's higher than a 3.8, so the bar is set higher. Another year the GPA's could all be around a 3.4. Sometimes someone doesn't measure up as far as GPA to everyone else but they are let in because of other strong areas they had. It can vary year to year.
To answer your question there is always a chance in getting in somewhere. I have seen the "impossible" happen when it comes to getting into school.
