Answer

Hi Sue,

Both of your sentences are correct.  It depends are who is eating the cookies.  If there are two or more people eating cookies, then "they were eating cookies.  If it is was a friend you saw, it would be "He/She was eating cookies when I came home from school."

Answer

They are both correct.  The pronoun could be they, she or he.  Some transgender people prefer they to he or she as well.

Answer

Both are correct.

Answer

The second one is correct. 'Someone' is singular. 
I saw some people, they were eating cookies. 'Plural'.
