Yes she is real.
Yes at http://www.spock.com/Sacagawea/pictures there are 4. But they are drawings. There are no real pictures.
I have a friend, he is part Native American, and is very influenced by his culture. He speaks many Native American languages. He said that it is spelled Sacajawea, (or Sacagawea, either is acceptable) and most people pronounce it that way. But the correct way to pronounce it sounds like sakakawea, but again it is not spelled like that.
The baby boy was named Jean Baptiste.
The real Sacagawea never posed for a portrait, and she died before the invention of photography, so no authentic images of her actually exist. The design used on the small dollar coin is an approximation of how she may have looked.
It was Jean Baptiste
Yes; Sacagawea is just different spelling version of Sacajawea.
No, she was a real woman, a Shoshone woman who guided Lewis and Clark when they made their historic journey west.

Sacagawea
