It depends on who you are talking to. Spanish verbs are conjugated differently when the subject is considered either formal or informal to the speaker."Necesitas Algo?" should be used if you are speaking informally, like to a child, employee, or friend."Necesita Algo?" should be used if you are speaking to an employer, a parent, someone older than you, or a stranger.
Informally, it would be "tu hermanastra." In a formal context, or when speaking to a stranger or someone older than you, etc., it would be "su hermanastra."
You would say "She is older than her." "Her" is the correct pronoun to use in this comparison.
"Heself" is a reflexive pronoun. It is a non-standard and archaic form used in some dialects or older texts, where "he" would be the subject pronoun and "himself" would be the reflexive pronoun.
Thou is a pronoun, specifically a second person singular pronoun. It is an older form of "you" used in Early Modern English.
The word "thou" is a pronoun. It is an archaic or formal way of addressing someone directly in the second person singular.
Vous avez..... ? (for a stranger or someone older than you) or Tu as..... ? (for a good friend)
"or older" (talking about a living being) = o yotehr yashen (או יותר ישן)"or older" (talking about an object or city) = o yotehr atik (או יותר עתיק)
