Yep. There's no problem with using 'an' anywhere you want to. You shouldn't use and at the start of a sentence, though.
You can just about use any word possible to start a sentence
Well that is a tricky question but i would say at the start of a sentence people would often use "I" at a start of sentence. There is loads of words to start a sentence so i can't tell you all of them obviously. example: "I" went to the shops to buy sweets.

Yes, it is generally acceptable to start a sentence with "but," particularly in informal writing. However, it is best to use this approach sparingly and ensure that the sentence structure is clear and the use of "but" is appropriate for the context.
yes specially if the sentence is an interrogative sentence. for example "From where does this package came from".
use it at the start of the sentence e.g "rest assured, my deed will be done"
