Assuming you are talking about a first class letter stamp (regular stamp) then yes, however the current first class letter rate is 0.44 cents, so you would need to either use 2 on a letter (so that it equals more than 0.44), or buy 0.01 cent or 0.02 cent stamps at the post office (or online at usps.com) to add in order to bring the value up to 0.44 cents
A US first class stamp dated 2002 is worth face value only, and it's still valid now.

Yes, you can still use a Forever stamp issued by the United States Postal Service in 2009.

The stamp is called the "Forever Stamp" because it will be valid forever for a first class envelope.
It's a version of the Forever stamp, originally sold for 45 cents, and it's still valid now.
A postcard stamp looks like a first class stamp, only it has a smaller value. The size of the stamp is one inch by one inch.
