After you download the themes, you'll need to extract them to your /wp-content/themes/ directory. Then log into WP and activate the theme from within your presentation panel.
The themes are licensed under a GPL license. Basically, this means that you're free to do what you like with them as long as you redistribute them under the same license. I do have a small request: If you do use one of the theme, could you send a link back this way? Of course, there is no obligation to do this other than professional courtesy but I would definitely appreciate the gesture. :-)
The themes will always stay free, but donations are very much appreciated and will help continuing WordPress themes development and to provide support — donate via PayPal. I like to design things like these, but it isn't an easy job as it seems.
