|Those are APIPA addresses.|
This doesn't necessarily mean you're being hacked though. There could be a lot of reasons why those are showing up.
Here's a couple basic security things you should know and do:
1) If you have a wireless router, disable the ability to manage the router from the wireless network
2) Always encrypt your wireless network with WPA encryption and a complex password
3) Disable remote management of the router.
As to what those addresses are, there's no way for anybody to say without being at your desk and logged into the mangament interface on the router. I suspect someone is trying to connect to your wireless network. It could be as simple as a iPad or smartphone in the house that you've forgotten about or it could be someone with a laptop outside your home (like a neighbor) trying to connect to your network.
It matters not how straight the gate,
How charged with punishments the scroll,
I am the master of my fate;
I am the captain of my soul.
