The running female is Samsung Health.
The message icon is just some message app (and by "message" I mean "probably SMS"). There are hundreds of them, so unless someone uses exactly the same app chances are "some message app" is all we'll get. There isn't a standard app for this, as most manufacturers use their own and then many users replace that with one they prefer, but as everyone has at least one message app I don't think you can draw any conclusion from it.
