Does anyone have any idea of whats going on?
They come and go as attached devices in my attached devices list.
I also attached my routers log for you all to see. http://pastie.org/8997306

Looking at the OUI, it appears you have 3 Apple MACs connected, 1 Netgear MAC, and 3 unknown MACs.
The Apple and Netgear MACs may be spoofed; please compare them against your own devices. Then, if you can, compare their traffic against the legitimate device's traffic to see if those MAC's are being spoofed.
The unknown MACs are almost certainly spoofed. Note that I don't see 120.91 in the log snippet at all, which is interesting.

If you're concerned (I would be, but I'm overly concerned about security), I would:
These are not real devices. Your network device has some sort of memory fault and is displaying memory as "addresses". You can see that the device names contain sections of some JavaScript-like code. The IP and MAC addresses, when ASCII-decoded, show similar data:
120.91.105.43 = 'x[i+'
32.97.44.32 = ' a, '
34.99.101.110 = '"cen'
63:20:3d:20:69:69 = 'c = ii'
20:62:3c:74:64:20 = ' b<td '
42:43:3a:33:42:3a = 'BC:3B:'
Not coincidentally, the "BC:3B:" in the last address is the same as the beginning of your first MAC address listed, which @Anti-weakpasswords notes belongs to an Apple device.
I would recommend rebooting your device, and checking for any available firmware updates from NETGEAR.
