I'd say currently it provides too less information. Personally I think a "complete" solution would be nice, with:
activity if enabled
followers + following
To structure this a bit, you could use a viewpager + tablayout, just like the repository/orgs detail page, or a "tap-to-show" as already used in the repo details for general information and README.
The problem with such a popup is that you can't put much information in it without being overloaded. Personally I think a separate activity/fragment wouldn't be bad, since you can put much more things in there - a popup is just something for small things like warnings or simple questions, but I wouldn't use it to display more there.
But I agree with @opyale idea to use some icons and I also understand if you don't want to display more information than the general - but for me it would be useless in this format. At least the repositories should be included.
