Lots of my apps will no longer open 10.9.4

Question

Hi,
I’m running a 2013 MBP retina 13" on 10.9.4 (2.6 GHz with 8GB Ram) and lately lots of apps have stopped working. Messages, app store, mail, calendar and a few others.
The app bounces in the dock once, nothing happens, then it returns to whatever app was active before.
My Safari (7.0.5) also fails to load pages half of the time even though I’m connected to wi-fi. Chrome works fine, but I would rather stick to Safari if I can get it to work again.
Has anybody else had a similar problem? If so how did they resolve it?
Best,
–Bobby

Launch the Console application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Console in the icon grid.
The title of the Console window should be All Messages. If it isn't, select
          SYSTEM LOG QUERIES ▹ All Messages
from the log list on the left. If you don't see that list, select
          View ▹ Show Log List
from the menu bar at the top of the screen.Click the Clear Display icon in the toolbar. Then try the action that you're having trouble with again. Select any messages that appear in the Console window. Copy them to the Clipboard by pressing the key combination command-C. Paste into a reply to this message by pressing command-V.
The log contains a vast amount of information, almost all of which is irrelevant to solving any particular problem. When posting a log extract, be selective. A few dozen lines are almost always more than enough.
Please don't indiscriminately dump thousands of lines from the log into this discussion.
Please don't post screenshots of log messages—post the text.
