/dev/sda2 is your root partition (mounted as /) and where your OS and
all application is installed. It's 19 Gb and not 50 as you think and
you have 6 Gb free space on it. 6Gb should be enough as you have a
separate partition for your data (sda5 and sda6).

tmpfs stands for Temporary file system
(http://en.wikipedia.org/wiki/Tmpfs) and don't use any space on your
hard disks, it uses your RAM and grove dynamical and it at will most
use half of your RAM (8/2=4Gb).

You have to use your common sense to what package you can remove. If
you in Adept or Synaptic marking the package you want to remove and it
want to remove a lot of others to that looks like they belong to the
OS ask on the list and I'm sure someone can answer if it's safe to
