user4304: Self explanatory title, Most of the sites i have visited, Only allow downloading one game at once, So if i want to download several, It takes ages. So, is there is a website which allows downloading several pgn master games at once?

user825: http://smallchess.com/Games/Magnus%20Carlsen.pgn for games on Magnus Carlsen. It doesn't need to be unzipped as in pgnmentor, it's also more recent (includes the recent world championship).
Alternatively, you can download games for free at: http://smallchess.com/Games/ . Again, no need to unzip anything.
Updated: I own the site and personally prepared those files.

user657: If you're only getting one game at a time, you are really hitting the wrong sites. There are literally thousands of sites you can do collections at, ranging from the University of Pittsburgh Chess Club, to Mark Crowther's excellent This Week In Chess to New In Chess's pgn versions of the games in their yearbooks and magazines. Google is your friend, in this case, because there are far too many to list in a forum post: "PGN Chess games" yields over 6 million hits and "PGN chess games database" over 300K of them. Have fun.

user8690: I maintain a large chess games database, you can download it (and even contribute) here:
https://sourceforge.net/projects/codekiddy-chess/

user19786: ".pgn" file chess game databases can be opened, viewed and edited in apps that run on Android, Windows, Linux etc. There are many download sites, depending on what your looking for. For current event games try 
The Week in chess
For comprehensive collections by players (mostly grandmasters), events or openings try
PGN Mentor downloads
For annotated PGN games (which are very hard to find) I have added 950+ to my website in 9 separate downloadable ".pgn" files at
Annotated PGN games

user3270: http://www.pgnmentor.com/files.html
Allows you to download by player, by opening or by event where the game was played.
