For example:
"ntpd" is the network time daemon which synchronizes your clock with a network-time-server.
"slpd" is the "line printer daemon" used to communicate with network printers.
"nmbd" is part of the Samba distribution and used by Mac OS X for windows connectivity.
"configd" is the system configuration daemon which manages your system configuration, like active network interfaces, current network location and so on. You should at least allow configd to connect to 0.0.0.XXX using protocol IPV6-ICMP.
"mDNSResponder" is part of Rendezvous.
"natd" is the network translation daemon, necessary for the internet connection sharing feature.
To get more info about any of them, simply use a google search or open the Terminal application and type "man commandname" (e.g. "man ntpd").
"local network" stands for all your local networks on all your active network cards (including airport and so on). It is computed from the network interface's current IP address and netmask (depending on the number of active network interfaces it can stand for more then one IP-range). And it is recomputed if you change your "Location".
"localhost" means connections which are local on your machine, like connecting to a local USB printer.
"169.254.0.0/16" is the zeroconf/rendezvous address space which isn't routed over the internet and only valid within your local network.
"multicast" is an alias for the full multicast IP range 224.0.0.0/4 or 224.0.0.0 - 239.255.255.255. These addresses can be used for efficient distribution of (e.g.) streaming data like internet radio, if your provider and the application you use support it.
"broadcast" is an alias for the broadcast addresses of your local networks. Broadcasts are limited to your local network and won't be routed over the internet. You can deny broadcast for specific applications, however you shouldn't disallow broadcasts at all. There are also a lot of system daemons which rely on broadcasts.
If you need more in depth information about network ports and protocols, please try a web search. You will find lots of introductory articles like e.g.:

See. Now that wasn't so hard was it? This should be included with Little Snitch in a text file.
