There are multiple different files here, corresponding to the different desktop environments..
The files here are bittorrent files. Use a bittorrent client program to download the contents of the complete ISO image files in a peer-to-peer manner. You should end up with an exact copy of each ISO image as though you'd downloaded it directly via HTTP or FTP.
Once you have downloaded all the ISO images you want, you will typically need to write them to media, either writeable DVD or a USB stick.
There are files here (SHA512SUMS, etc.) which contain checksums of the images. These checksum files are also signed - see the matching .sign files. Once you've downloaded an image, you can check:
For more information about how to do these steps, read the verification guide.
For convenience for some users, this unofficial alternative build includes non-free firmware for extra support for some awkward hardware.
Live images tend to be resource hungry by nature - they need to use memory to extract and store the compressed system as well as the memory that the running software would normally need. The minimum recommended RAM for using a desktop environment on a live image is 2 GiB. If you have a system with less memory, your system will not work well here.
