The fallen angels do. (The ones that followed Lucifer known as Satan)
The good angels are all angels that have not fallen.
A demon is a jinn. Jinn are made of smokeless fire (plasma), they have freedom to pick sin if they please. Angels do not have freedom to sin, they happily worship and follow God. The angels were made out of Light.
Yes, the Bible gives several accounts of angels sinning, i.e. Lucifer and his fall from Heaven because of his pride and greed.
The Father gave angels and mankind free will.
Angels are believed to have free will in the Judeo-Christian tradition. They are considered to have the ability to choose between right and wrong, and to make decisions based on their own moral reasoning. Unlike robots, angels are understood to have individual personalities and the capacity to act independently.
A Archangel would be called a saint because they are high-ranking angels in heaven, and since they are angels, they do not sin, so they would be a saint.
no, but good angels can protect you from the bad angels(who are now demons)
There are two types of angels in the bible. They are the good angels and the fallen angels.

yes there is sometimes a good reason for people to sin
because they are created by god so they are already saved According to most religions, aren't we all created by God? If so, why must we then ask to be saved or follow some sort of religion to get into heaven if being created by God means we're already saved? According to most Christian religions, angels are servants without free will and therefore are not capable of sin. People were given the gift of free will and are prone to sin. Personally, I like sin so I guess it's a good thing that I'm not a believer.
