This will actually depend on where you are from when you travel to the USA. The most basic is that you have to have a valid passport with about 6 months left in it, Visa to enter the US (again, this depends on where you are from, there are some that need not to have a visa to enter), a valid identification card and your ticket to and from the country.
Yes, you can travel to Dubai with a US refugee travel document.
I have vacationed in the Dominican Republic, and the only document I had to have was my passport.

no
No such document is required for a US Citizen but that time will surely come someday.

The question is a bit confusing. You might want to clarify. A travel document is a passport-like document given to a LPR (legal Permanent Resident) when they like to travel outside of the US for more then 6 months. If you are outside of US and wanna travel to US, yes you need a visa.
For international trips, the original passport is typically required. Copies are not usually accepted for travel.
No, it is not possible to travel outside the US without a passport. A passport is a necessary travel document for international travel.
It is not possible to travel internationally without a passport. A passport is a necessary travel document that is required for crossing international borders.
Only when you are from the US
All you need is a valid passport when u travelling from India to Nepal or vice versa.
