You have a major problem here in that you are using muddled words. You don't learn anything by asking questions based on one meaning when people can answer based on several different meanings.
1. Do you identify with a particular religion or worldview?
I am Christian. That is not a religion. Being a Christian is a relationship. Religion is made up by men telling each other what to do. I have no idea what you mean by "worldview".
2. Do you believe in God, a deity, nature, or the universe?
That is a very mixed up question and you will only get mixed up answers.
3. What happens to a person at death? (Heaven, Hell, reincarnation, etc)
The soul dies when the body stops breathing. The body rots and the spirit of lilfe returns to God who gave it. Hell is a hole is a grave. Check any dictionary. Everything most people believe about hell came from one fictional book by an Italian guy named Dante Allighieri, based on Roman Catholic traditions.
4. If you are religious, how does one access Heaven? Why do people go to hell? How does one be reincarnated?
4. What is the meaning and purpose of life? Or is there a meaning & purpose?
My bible says mankind was put on Earth to take care of it.
5. How do we know what is right and wrong?
If it hurts, it's wrong.
6. What is a human being?
There is a scientific definition, although it covers several different animals.
7. What is the nature of the external reality, that is, the world around us?
What is this "nature" of which you speak? That word has a lot of meanings and there is no profit when you use one meaning and I use another.
