If you are indicating possession (Achilles' heal) use an apostrophe at the end of the word. If you are simply stating his name, there is no apostrophe.
No, unless your name has an apostrophe in it or you are using it in the possessive.
Achilles is a name, so you can use it the same way as any other name.
No, only use an apostrophe when using a contraction or a possessive
You only use an apostrophe in it's when it is a contraction of it is. If you are using ITS to describe something belonging to IT, such as "It was wagging its tail," then the tail belongs to it and so its does not have an apostrophe.
It's is the contraction for it is....so if you are using the contraction, use the apostrophe. If you are not, then do NOT use it.

Yes, you do because the apostrophe, in this case, shows belonging. The name belongs to your mom.
Only if the title is a proper name, that is, if Carolina Girl is the name of a group. Then you must use the apostrophe to show possession. If the name of the group is Carolina Girls, then no apostrophe is necessary.
Yes, there can be either apostrophe s ('s) or just an apostrophe (') at the end of the word.
Use an apostrophe to indicate the following: Possession - This is the boy's ball Contraction - I can't believe that! Omission - His name is O'Hara
An apostrophe is used in a proper name to show possession. Leah's dress, David's voice, and Justin's hair, for example.
