I noticed some applications in Android (like Facebook, WhatsApp, Google Maps and ShopSavvy) have a similar title bar with a button or more on the right corner. I know how to implement a custom title bar, there are plenty of examples here on stack overflow, but I feel like there’s a library or some kind of pattern to implement them, since their sizes, icons and separators are similar. I already have a custom bar I created myself, but I’d like it looked like these ones. Are these custom bars too? Any help?

The iosched app is a great reference for the Dashboard and ActionBar UI pattern Google presented at their I/O conference in 2010.
Beside that you might also want to take a look at the GreenDroid project, an Android library project that helps you implementing those best practices UI patterns like ActionBar, QuickActions etc..It’s free and available here: http://android.cyrilmottier.com/?p=240
