I think I understand, but I might not...
The question I think you are asking is how do I compare multiple variables across 4 different groups. The way to do this is just to do the same tests against one group and then to do it again across another group. You will get means and proportions then for each of the dichotomous outcome variables.
Now, you may run into issues/questions regarding the age old problem of "correcting for multiple comparisons". Generally speaking in your context I do not think you need to correct for multiple comparisons. However, this would require some discussion in regards to your data, and yes for this class I think this is probably not the objective of the assignment. For this assignment if you just choose one of the dictotomous outcomes and compare it across your other variables you will have completed the assignment.
