What is the difference between a laser pointer and an infrared laser pointer?

An infrared pointer uses light that is mainly in the infrared spectrum, and so is mostly invisible to humans. A laser pointer in general refers to any device using a beam of light to mark an object. Both use the same basic technology. The only difference is the wave length. IR lasers are outside of the visual spectrum where as standard laser pointers are within the visual spectrum.

How will you measure the thickness of human hair?

If you get a normal red laser pointer, you can pretty easily measure it at home. The wavelength of a red laser pointer is typically around 670 nanometers, the one you select may state differently; make note of it. Take one of your hairs and suspend it in front of the laser somehow, but make sure its exactly 1 meter from a flat surface. When you turn on the laser, you should see a dashed line pattern on the board. Measure the distance from the center bright spot to the farthest bright spot you can see and count how many this is. The thickness of your hair is (laser wavelength)*(distance to flat surface)/(distance to bright spot). Then multiply this number by the number of bright spots you counted. So, lets say i could count up to 4 bright spots before it got too dim; i measure the distance from the center to this one to be 5 cm; laser is 670nm and my flat surface is 1 meter away. My thickness is (670*10^-9)*(1)*4/ (.05) = 54*10^-6 meters = 54 micrometers

Will a laser pointer work at laser tag?

No it won't. Laser pointer simply emit a laser beam whereas laser tag systems use other methods to register tags. The laser in laser tag is for effect. The actual laser doesn't tag the pack.
