Hi,

since all the mentioned softwares are open source, no need to pay money

For shareware (as opposed to freeware), you need to read the terms set forth by the author of the software. He may require (though maybe not through a license key, etc) that if you use his software, you send him some $$$.

Good shareware is often a great deal.
