If it's correct and it doesn't specify to solve the problem using a different method then yes.

They are allowed but as a rule of thumb it’s best to stick to non-FM methods because the questions are designed so that standard methods are often the most efficient. Only use FM methods if you have a good reason to do so.

Yes, this is fine, and you will be credited. It's probably quicker in some circumstances. (eg. using the dot product to find the angle between two vectors vs finding magnitudes and applying the cosine rule, though they amount to the same thing) Though I can't think of many instances where it'd help you much considering a large chunk of vectors was moved to FM.
