I am trying to install Skype and Google Chrome on my desktop. It runs Debian 5 32-bit. I downloaded the packages from the web but I have no idea how to install them.

There are options for installing software without root access. First of all, using the sources (if available) you can build and use most packages as a non-root user -- but this "from sources" way forces you to deal with dependencies, as well. Starting from that, pkgsrc makes this easier, by offering a large number of, say, recipes to build packages and their dependencies (so-called "ports"). It supports non-root operation, see this FAQ entry. There is a guide on how to use pkgsrc here.
Regarding the packages you're looking for, they have "ports" in pkgsrc: wip/chromium
, net/skype21
. (Where Chromium, the Open Source project related to Google Chrome, is available as a work-in-progress package only, i.e. via wip.sf.net
, a repository of additional ports to pkgsrc.
Also, there is ZeroInstall, which as far as I know provides binary packages that you can install in some way not requiring root permissions. (Of course you need to install ZeroInstall first, which you can -- if your sysadmin doesn't install the zeroinstall-injector
Debian package for you -- install from source, too, as explained here.) I'm not sure if this way is less involved, though. (From a quick look, they seem to have Chromium and Skype packages, but the first one looks kind of old.)
The bottom line: it is possible, but involves some work and things to learn (which can be considered a good thing, while time-consuming). The easiest way probably is calling your sysadmin to install the Debian packages you want to use.

If you want to install a package with a double click, first you should install an application that with handle that. In a terminal write
sudo apt-get install gdebi
if you do not have a root password, or
su -c 'apt-get install gdebi'
if you have a root password.
After that the double click in the filemanager should work.
Google Chrome, in the unbranded version called Chromium is available in the package chromium-browser
, so no need to download the package, simply run
sudo apt-get install chromium-browser

gdebi
-- orsudo
for that matter -- is meant for the sysadmin to make his own job easier without having to su to root for everything, not to give random users admin privileges... – Shadur-don't-feed-the-AI Jan 21 '12 at 22:24
