A small faq is here: http://www.1001freefonts.com/faq.htm
It says
Q : Are all the fonts on this website free?
A : The majority of fonts on this website are freeware, but a small percentage are shareware so if you decide to keep any shareware fonts please register them. Registration information can be found on the readme.txt file attached.
Perhaps you already know of it but this site http://www.dafont.com/ has a lot of fonts and for many it says (above the download link) whether they are freeware, or free for personal use, or shareware.
