That depends. Anyone from a Shengen Agreement country may travel to any other Shengen Agreement country without a passport. US citizens and Canadian citizens may criss-cross the border by land without passports. (for now...) There are other examples out there. Please reask your question with more specific detail, such as "Where can a Zimbabwean travel without a passport". If you REALLY mean what your question implies, then the answer is "NO". All countries have some sort of passport requirement for entry by some (or most) other country's citizens.
I do not know where you are but any international flights require passports.
Excepting the passport's home country, most countries worldwide will require your passport to be valid for a minimum of six months. Entry requirements for any country are subject to change and it is advised that you check with the local embassy/consulate for the latest passport/visa requirements prior to your travels.
THIS IMPORTANT! Some countries do not allow a person to have their Passport and any other. This is punishable with penalties of Passport and Citesenship Revocation to DEATH. Many many countries allow persons to cary and posses two passports. I have Canada and USA Just rember most countries only allow you to enter and leave on the same one. SO rember what one you used!
This depends on the countries of your departure, arrival, and any other connecting countries as well as your country of citizenship. If you fly across borders, you will need a passport. Some countries require visas, proof of immunizations, proof of return travel, proof of lodging and money, and stuff. Check with your airline. They'll be able to give you better details.
Any colour.
You can hold a passport in any country you are a citizen of however, if you have dual citizenship you need to be sure both countries allow for dual citizenship.
i dont have any idea in that question
No. You need a passport to get on the airplane and go through customs. If all ready in EU nations you don't need passports to move between countries., but if you go in places like Russia a visa is needed.
