Yes, for example:
'Twas the night before Christmas, when all through the house.
There is no reason why an apostrophe shouldn't be used at the start of a sentence. However, the question you next need to ask yourself (the one I was searching the net for when I found this) is "is the first letter after the apostrophe an upper case or not?!
No, you do not need to use an apostrophe in the sentence "I have two cousins." Apostrophes are typically used to show possession or to indicate missing letters in contractions.
yes becasue cousins is plural you would do this: cousins'
No, the word "skittles" does not have an apostrophe in a sentence. An apostrophe is typically used to show possession or contraction, which is not the case for the word "skittles."
No, an apostrophe is used to indicate possession or contraction, while a comma is used to separate elements in a sentence. They have different functions and cannot be used interchangeably.
It depends on the sentence. If it's a contraction of the words "it is" then there is an apostrophe. (See this sentence for an example) If it's to indicate possession it doesn't. (Ex: The old coat lost its button.)
The best way to use an apostrophe in a sentence is to show possession or to indicate a contraction.
Yes. 'Its' in that sentence is short for 'it is' so it should have an apostrophe.
The apostrophe in the word Billy's means Billy's ownership of something.
example:Death,where is thy sting?
No apostrophe is to be putted in this sentence.
Meet me in the engineer's office.

yes
It is appropriate in some situations. There are two ways to use "its": as a possessive or as a contraction. When you use it as a possessive, there is no apostrophe. For example: The dog wants its bone. When you use it as a contraction, you use "it's." For example: It's my cookie. The sentence could also be read as it "It is my cookie;" therefore, "it's" is a contraction in this sentence and requires an apostrophe.
The term it's is a contraction of the words it is with an apostrophe, and is often confused with its, which means the possession of a thing, but without an apostrophe.
You don't have an apostrophe in your sentence. You don't need one either.
