ELI5: Can you denounce your citizenship and be technically and officially a citizen of no country?

1.Is it possible to denounce your citizenship and be a citizen of no country?

2.If this were possible what would that look like on official documents and would it be impossible to get a passport?

3.Can you also renounce this citizen ship in later time?

4.Is it also possible to renounce and denounce your citizenship constantly? As in, there is no limit to how many times you can become an american and then subsequently denounce your american citizenship? 

5.Finally is there a limit to how many citizenship you are allowed to have? 

6.does renouncing or denouncing a citizenship have any effect on this?

7.If you were to have 2 citizenships and another country would not recognize you as a citizen unless you remove one would that mean your technically force to denounce a previous citizenship to become a citizen of that specific country?

It's called statelessness, and it's possible. More often it happens at birth or involuntarily. Several UN conventions have aimed to reduce it. However, the U.S. hasn't signed them, and unlike many countries, will allow citizens to renounce their citizenship with nothing to replace it. This has happened at least a few times. Renouncing U.S. citizenship as an adult is irreversible.

You don't want to be stateless. No country is obligated to give you a passport or legal documents, provide protection or services, nor even to take you in. You can be in limbo indefinitely.

There's not an obvious limit on multiple citizenships, though it's hard to get more than a few. Some countries won't allow their citizenship to be held in combination with others.
