The problem here is that BankAccount, BuckysButtons, multiview, rotator and segmentedControls are all git submodules, which act like independent repositories in many ways.
If what you want to do is to run git add -A . in each submodule, you could do:
git submodule foreach --recursive git add -A .
And then you could create a commit in every submodule with:
git submodule foreach --recursive "git commit -m 'Committing in a submodule'"
(If you don’t have other submodules nested inside those submodules, the --recursive option is unnecessary.)
However, I don’t recommend doing this. You should carefully change into each submodule in turn, and consider how you want to update them, treating each as a standalone repository. Then only commit these new submodule versions in the main project when you have tested that the project as a whole works with those new versions of each submodule.
Update: It seems from the error message that you’ve quoted in the comments below that you have added these other git repositories directly rather than as submodules. This can happen if you copy another git repository into your repository and then just use git add to stage it, rather than adding it with git submodule add <REPOSITORY-URL>. If you really intend these to be stored as submodules, I would suggest moving them out of your repository, committing their deletion, and then add them properly as submodules with git submodule add
