Can Christians provide an all-agreed (among Christians), concrete description of Heaven?

I do not believe in afterlife, but this is NOT a trolling. I really do want to hear what Heaven is actually like, not a vague idea like "a wonderful place".

My question may be vague, so I have some specific points which can be answered with true/false. Can Christians have a unified answer for these?

1. Are there dogs and cats?
2. Are there computers (including mobiles, gaming consoles, etc)?
3. Are there foods (real, not like 'food-for-thoughts') for us to eat?
4. Is there entertainment like TV shows, movies, or songs? If so, are they imported from Earth, or are they created by people in Heaven?
5. Are all people in the same, connected world or are groups of people in discrete worlds (that cannot interact with others)?
6. If the answer to 5 is true, do people in Heaven have some political entity to discuss the policy of how the life in Heaven should be?
7. If you somehow feel bored of your eternal life and do not want to live anymore, can you choose to stop existing?
