For most modern bikes you will need a tool with at least 4, 5 and 6 hex wrenches and a phillips screwdriver. Make sure that the various bolts on your bike can be tightened by the tool you got. You will need a separate tire lever (usually two of them) to deal with flat tires.
One for every removeable or adjustable part on your bike (including tyres). With the exception of those you will be unable to repair/fix on the trail, such has hubs and bottom brackets. They need not all be combined with one tool though (sometimes individual tools can be lighter)
PLEASE ADD THIS AS A COMMENT AS I STILL CANNOT POST COMMENTS!! I bought a multi-tool set (for about £3.99 in the UK, $5.50 in US roughly) from a bike shop (Evans cycles) when I bough my bike.

A pump is handy too so that you don't have to walk your bike to a gas station if you get a ...
Minimally, you want to be able to tighten all of the bolts on your bike (likely a few hex keys will do this) and an appropriate screwdriver for adjusting derailer & brake pulls. Separate from a multi-tool, a pair of tire levers are the other tool you should carry with you. I would add a chain tool to the above list after being left in a state where I ...
First, you need to familiarize yourself with your bike. If you're not familiar with your bike to begin with, you'll have a really hard time buying the right tools for it. Once you have an idea of which tools you'll actually need, then it will be quite clear which multi tool to buy.
