Well yeah. Its called a theory because it wasn't proven right yet. Once proven right, its called a fact.
Yes ... in theory. Scientific knowledge is always provisional knowledge, that is, not absolutely certain. However, it is very, very rare for a well established scientific theory to be completely overturned. Ordinarily theories are refined by correcting small errors, or by filling in missing parts. Relativity 'superceded' Newtonian Physics, but it did not replace it or find it wrong. Rather it extended it into new realms, and provided a new basis for Gravity (among other things). See the entry for "Theory" in Wikipedia for more. (And always remember, the meaning of "theory" in science is not the same as the meaning in ordinary language, where theory is often used to mean "hypothesis". In science, "Theory" means a well established body of laws and facts.)
It is a well-established, well-tested, well-supported, comprehensive model for the explanation of a well-defined set of observations in various branches of science. That is the definition of what a scientific theory must be, and thus evolutionary theory is a scientific theory.

true
This would be called a well established theory.
A well-supported hypothesis is a theory that appears to have a lot of evidence behind it. This evidence helps to make it seem likely that the hypothesis is true, but it is still just a theory until it has been proven.
