I've never really understood temperature and the science around it.
When something reaches absolute zero, does it still have a temperature?
Can an object have no temperature?
If you can answer this in Layman's terms, I thank you.

Everything always has a temperature, when something reaches absolute zero, then it's temperature is 459.67 degrees Fahrenheit so of course it has a temperature.

No, an object must have temperature.
Even if an object IS O degrees, it will still have a temperature. Thinks about any object, it will have temperature of some variety (on a molecular scale, the particles bouncing off each other is what gives off the temperature, this is more complicated but you may investigate further if you wish)
Things may feel to the touch as if they dont have a temperature ("hot" or "cold"), the closer they are to the standard body temperature of 37 degrees celsius, as your body cant sense the difference in temperature. Such objects still do, of course, have a temperature
hope that helps

It can be shown from the laws of thermodynamics that absolute zero can never be achieved artificially, though it is possible to reach temperatures arbitrarily close to it through the use of cryocoolers. This is the same principle that ensures no machine can be 100% efficient.
At very low temperatures in the vicinity of absolute zero, matter exhibits many unusual properties including superconductivity, superfluidity, and Bose-Einstein condensation. In order to study such phenomena, scientists have worked to obtain ever lower temperatures.
In September 2003, MIT announced a record cold temperature of 450 pK, or 4.5 × 10-10 K in a Bose-Einstein condensate of sodium atoms.

Temperature is like water level but is a measure of the energy of a system. If it is at the lowest level possible, it cannot get any lower and there is no reference to talk of its level. Similarly at 0 K, the concept of temperature becomes meaningless. But as mentioned in one of the good answers, it is not possible to reach absolute zero.

Temperature is really just a measure of energy. At absolute zero, particles have no energy, and effectively no temperature. That is also why you cannot have temperatures below absolute zero.

Temperature is a manifestation of heat and atomic motion. At absolute zero, all atomic motion ceases, but there is still a temperature of 0 kelvins.
