"Can someone name them all" - You've got to be kidding.  There are a lot of defenses to  1.d4, you need a book or use the game explorer on this site.  Good luck!

With 1.d4 d5 2.c4, you've got...

2...cxd - the Queen's Gambit Accepted

2...e6 - the Queen's Gambit Declined

2...c6 - the Slav

and a couple others that aren't quite as popular.  From these, you may see your game evolve into a Semi-Slav, a Noteboom, or any of a trillion other popular lines.

From a start that goes 1.d4 Nf6 2.c4 g6, you've got the King's Indian and the Grunfeld.

From a start that goes 1.d4 Nf6 2.c4 e6, you've got the Nimzo Indian, the Queen's Indian, and the Modern Benoni.

If instead of 2...e6 you get 2...c5, you can still see the Benoni, or maybe the Benko Gambit.  (Or others, but those are the most likely.)

1.d4 f5 is the Dutch, with its several sub-variations.

Those are the most major of the major variations, most of which see white playing 2.c4.  (Or at any rate, c4 before too many moves have passed.)

If white chooses not to play c4, you've got a whole bunch more, including the Colle and Colle Zukertort, the London, the Trompowsky, the Stonewall Attack, and others.  These, you can figure out on your own.

That's far from comprehensive, but the names should give you some starting points for things to look up on google if you're interested.
