What are some synonyms for one and another?

Answer 1

Do you mean when they are used together ... as in "the sisters were always with one another on the playground" -- or what?

You can always go into http://www.thesaurus.com to look them up. But you need to know if you are looking for them as nouns or as adjectives.
