Purgatory (Barzakh)

My question is regarding purgatory, what is the life of the dead like in purgatory? And do they meet with others and visit the dead and the living? And do they eat food and drink water? And what about the good deeds which we perform for them?

When were the jinn first created?

When the jinn first created? And are they from the previous worlds or they were created with the creation of the prophet Adam pbuh? And what are their lives like? Do they have prophets and messengers? And do they go through what the human beings go through of tests and hardships? And do they partake in movements and wars with the human beings, meaning they fight the prophets and guardians or do they support them?
