That is a joke: Photons have mass? I didn't know they were Catholic! This is why you should always capitalize Mass when you are referring to the Eucharist so it is not confused with mass which means 1) a coherent, typically large body of matter with no definite shape or 2) the majority of.
The term for the small packets of energy emitted from light is called photons.
Photons.
No. All photons travel at the speed of light.
The energy of visible light can be measured in organized packets called photons. These photons have discrete values of energy, meaning there is exact amounts of energy these have, and don't vary in decimal places.
Photons do not come in different types like infared-photons etc. they are just the wavelength that the photons are at and nuclear fusion just happens to emit photons at a particular wavelength

Well, they're probably not really particles ... but they're called "photons".
Photons carry electromagnetic energy.
Photons. Lots and lots of photons. ;)
No, photons do not decay over time.
When light is emitted as particles, it is called photons. Photons are the basic unit of light and have properties of both particles and waves.
