Depends on country...at least a couple of weeks usually!
At least six months remaining before the passport expires. If you have a UK passport and want to travel to Italy you only need the passport to be valid. YOU DO NOT NEED 3 OR 6 MONTHS REMAINING FROM ANY DATE OUTBOUND OR INBOUND.
The validation of your passport must be for traveling from UK to Dubai must be really good and valid. If it is not, then you must validate it before traveling.
You can travel with valid Yugoslav passport until December 31, 2011. But you should note that you will need visa for most of the countries if you travel with such passport. It would be wisest thing to replace Yugoslav passport for new Serbian or Montenegrin passport.
There is no such thing as temporary passport. It is either you have a valid and not expired passport of your country of citizenship or not. You need this valid passport in order to travel to Thailand.
For the EU citizen, to travel inside EU (like from Ireland to Poland) a valid ID is required, but not necessary a passport.
No, you cannot. Passport must be valid.
You can travel within the US with a green card so long as it is valid. A green card is NOT a valid document for international travel outside the US. To travel outside the US, you will need a passport and possibly visas depending upon the passport you hold and the country you visit. Please check with the local embassy/consulate for the most up to date visa requirements for your country's passport prior to travel.

According to the State Department website and the airlines (USAirways) your passport just needs to be valid for your travel dates. As long as you are back before your passport expires, you are OK.
It is not ok to travel on an expired passport. Why? because even though the country you want to enter accepts expired passports (which there is no such country), the airline will not allow you to board the aircraft. So, always make sure you have a valid passport and proper visa, if you need one, well before your departure date.It does not matter if you are a new born or a 97 year old senior- you should have a valid passport to travel outside your country.
I may be wrong, but all you need is an I-94 form and your Mexican passport as ID
This will depend on where you want to travel. If only within US then you need a valid ID, if international travel you need you passport, visa and other requirements like immunization and such.
