You can try out any of these distributions by getting or borrowing a copy of the Live CD and just booting your computer from it. The Live CD will not make any changes to your hard drive unless you ask it to.
You may see an icon on the desktop that you can click to actually install the Ubuntu (Kubuntu, Edubuntu, or Xubuntu) on your hard drive. If you don't care whether or not you erase everything now on your computer just go ahead and try it.
If you want to retain your Windows installation and/or other data and programs you already have, then you should read the instructions carefully. And it is always best to be sure you have backups of anything important, before you make any major changes to your computer.
For detailed installation instructions, this is a good resource: https://help.ubuntu.com/community/Installation (notice that the I in Installation is capitalized).
