In formal writing such as essays or book reports, you should almost never start a sentence with the word "well." This makes it sound chatty, and harder to read.
Example:
Why are comets called dirty snow balls? Well, they are made up of dirt and ice...
Try taking out the "well" and see how much smoother it reads. If you are trying to make your writing a little more chatty, it's okay to add well once in a while, but not every other sentence. If you can't stop adding that word, write it down anyway and take out a bunch of them when you are editing.

Well, that all depends on how you are trying to use the word..... Use it in context and that will help clarify.
The word and can be replaced by the ampersand (&) or by the phrase "as well as"; there is no single word that replaces it, however.
