Postage depends on which country you live in, how much the envelope and contents weigh, and where you are sending the envelope to. You'll need to include all that in your question to get the correct answer - or you could just go to your local postal website and get the answer from the experts...
The number of stamps needed to send a 9x12 envelope depends on its weight and the mailing service you choose. For a standard 9x12 envelope weighing up to 1 ounce, you typically need two First-Class stamps. However, if the envelope exceeds 1 ounce, you'll need additional postage based on the weight. It's best to check the current USPS rates or use their online postage calculator for accurate pricing.

One 49-cent stamp should be all that is needed.
At that size and weight, it would cost $2.20 (as of 2016).
If it weighs up to one ounce and is rigid and not extra thick you can mail it for 88 cents ( two first-class stamps). If it weighs 2 ounces the cost is $1.08. If it heavier or thicker, it will cost more.

To mail a 9x12 envelope weighing 3.8 ounces, you typically need two First-Class stamps, as the first ounce costs one stamp and each additional ounce costs an extra stamp.

As many as will fit. I have one envelope in my collection with 44 stamps on it! The sender used one cent stamps to mail it. Some people will overlap stamps to get more to fit, which is okay as long as the Post Office can plainly see that they are all there.
Depends all on the weight.
You would have to use 2 stamps to get a small envelope from Florida to Canada. If you do not want to use stamps, you can take it to the post office and it will cost roughly 72 cents to mail it.
