The F-22 uses a few systems, and lessons learned from the F-111 to be a Low observable aircraft.
The engines emit a heat signature that is unmistakable, but they have used heat hiding components in the belly, and a squared thrust vectoring exhaust to disperse the heat.
They use multiple angles on the fuselage to diffuse radar, interior mounted missiles or bombs, changed the intake to hide the compressor from radar, and a radar that can be aimed to reduce exposure.
One of the many ways to locate and identify an aircraft is by homing in on it's radar emission.
Radar absorbent coatings are employed to help reduce it's signature as well.

The F22 Raptor is a single seat, twin engine fifth generation supermaneuverable fighter aircraft that uses stealth technology. The average price of the F22 Raptor is around 150 million dollars.
Yes.
In an internal weapons bay, stored in the aircraft. It opens to fire the missiles, it does this because if it had the missiles on the wings, it is likely that these would reflect radar beams back to the enemy planes, therefore compromising stealth
Currently, the B2 Spirit and the F22 Raptor. The F117 Nighthawk has been retired, as has the 'reduced RCS' SR-71 Blackbird. The F35 isn't scheduled to be delivered until 2016.
F22 Raptor stealth, flexibility, and strikepower Eurofighter is amazing too -
The main feature of the F-22 would be it's stealth capability.
The F-22 stealth raptor is the stealth combat aircraft.

All stealth aircraft are built with the intent of being 'invisible' to radar. One of the best was the F-117.
The last cost I heard was in excess of 420 million per aircraft.
The T-50.
Fast enough to do the job. The actual maximum speed of all stealth aircraft is classified. Like any aircraft, the speed will depend on many factors.
