[Ubuntu-US-PA] Name these Linux applications?

[Michael Hodges]

So I'm a Freemason, and I was attending a leadership seminar for the organization, and noticed something pretty cool.  The guy running the slide presentation was using a Linux on his laptop.

I was just wondering though if anyone could identify three of the applications in his Unity launcher dock; the three above the Skype icon.  I was browsing through the Software store-like hub, and couldn't find anything that matched those icons, and didn't even know where to begin with a search query for "calendars applications in linux" or whatever.  The top one in green looks like it's specifically for Ubuntu, but I can't even figure out what it's mean to do, I mean it's just not immediately apparent (like the one below it as a calendar).

Anyone have any clues?
