Hi Ijaz, I'll say welcome, in case no one else has said it yet.
I don't have time to check, but your answers could be here.

What are Axions??
They are a hypothetical subatomic particle which has a very low mass, and which hardly interacts with normal matter.
- If they exist, they could have been produced in great numbers in the Big Bang
- If there is a lot of them, they could have a total mass far greater than the normal matter with which we are familiar
- If so, they could account for Dark Matter
- As yet, no experiments have found repeatable evidence for the existence of Axions
- At best, experiments have provided a set of masses and densities that Axions can't be.
Hard-to-detect particles would not be a novelty - it is very hard to detect neutrinos, and our Sun produces a large fraction of its nuclear fusion output in the form of neutrinos.
Axions... Why are they called angel particles??
I don't find that this is a common name for the (hypothetical) axion.
I recommend the Wikipedia article: https://en.wikipedia.org/wiki/Axion

A quick scan through the article shows it doesn't refer to Axions, but it is worth reading.
