That command has NOTHING to do with what is on your machine, it tells you what files containing 'linux-image' in the name or description are available in the repositories you use. (Or were, the last time you did an 'apt-get update', as it is reading out of the cache on your local machine.)
They are many because they include the original default kernel, any updated kernels, and the special kernels (patched for XEN, with or without Real Time patches, etc.). Generally, only one or two will be installed on your machine, but the others are AVAILABLE to install.
For a list of what is INSTALLED, use on of the gui tools (aptitude or synaptic, for example) or use dpkg to list installed software packages containing the 'linux-image' string. or for a very quick, just 'ls /boot/v*' to see the actual kernel files. Run 'uname-a' for an indicator of which is currently loaded and running.
