No, the article 'an' is never used before words starting with 'f'. The form 'a' is used. For example 'There was a frog in my garden' not 'There was an frog in my garden.'
The form 'an' is used before words that start with a vowel sound. Thus, you have correctly written 'an F' in your question, because the sound of the letter-name 'F' starts with a vowel sound: 'ef'.
quotation
A and an are indefinite articles. Use a before a word starting with a consonant eg A house, a boy, a girl. Use an before a word starting with a vowel eg an apple, an objective. But also use an before words of French origin starting with a silent h eg an hour, an hotel. See link for reference.

"Lab work" should be written as two words.
it's called prehistory

One millionth.
One thousandth.
Yep, like the words: "announce", "annoy", "annum".
Underdeveloped should be written as one word, not two words or hyphenated. I hope this answered your question. :)
The general rule in formal writing (that which you do for school or work) is yes. All numbers that appear as two or fewer words should be written out.
The article "an" is used before "honest" because the pronunciation of the word begins with a vowel sound. This follows the rule that "an" is used before words starting with a vowel sound, while "a" is used before words starting with a consonant sound.
Yes, both "a" and "an" are indefinite articles used before nouns to indicate that the noun is not a specific or known one. "A" is used before words starting with consonant sounds (e.g., a house), while "an" is used before words starting with vowel sounds (e.g., an apple).
In words, it is written as thirty six. It should be written as "thirty-six".
