Where you're at determines that. Some countries have five round magazine capacity laws, some states in the US have ten round capacity laws, etc. The answer to your question is going to be anything belt fed with a disintegrating link belt - they can be fitted together to form a belt of as many rounds as you desire. As for magazine fed firearms, the Calico guns come available with 50 or 100 round magazines. 90 and 120 round drum magazines are available for firearms which use a STANAG 4179 magazine interface (AR-15, Daewoo K2, Sig556, HK416, KelTec SU-17, etc).
Not usually. Machine guns are legal in most states, but not legal for hunting in all of those states. Plus, many states have a limit of the number of rounds allowed in a gun for hunting, usually 3 or 5.
Most paintball guns use an above hopper instead of magazines or clips like firearms. The standard hopper holds 200 rounds. Most magazines for paintball sim-markers are 30 rounds. No paintball guns use clips.
That number of rounds can vary. Most of us are familiar with revolvers that hold six rounds. Some pistol magazines can hold up to 13 and more. I know of one revolver with a cylinder that holds nine rounds.
The most common number of rounds a magazine will hold is between 8 and 16, depending on the caliber and size of the gun, however, some magazines hold a few more, and you can buy magazines for some guns that hold as many as 33 or even more.
There is a broad range of ROF (Rate of Fire). It can be anywhere from a crazy slow 3 rounds per second (some off-brand guns) all the way up to 100 rounds per second (Echo 1 M134). These are the ends of the scale, while most guns fire 10-20 rounds per second on fully automatic.
In most situations they are NOT legal in California. Source: California Penal Code Section 12301-12312
Anything belt fed will hold the most, most belts being around 200 rounds. More can be added to the end of the belt however so its really limitless. If your asking about something with a clip (not a drum, a clip) I'd guess FN P-90's are close with 50. Prolly could go google that though.
It depends on the pistol make and model, and what it is chambered for. Most semi-autos nowadays hold at least 12 rounds. Most revolvers hold six.

No exact record, since there is no requirement to register guns in MOST of the US. One estimate is 312 million owned by ordinary people.There are an estimated 200 million legal guns in the United States.
It depends, but most quality guns (Sig, Glock, etc) are rated for 40,000 or more.
On average, most gun racks can hold anywhere between 4 to 6 guns. Most gun racks that you hang on the wall holds around 4, whereas most gun racks that stand up can hold around 6.
