[Grammar] How we use unless, to, so that, wish, would rather, and had better

[Unregistered pony]

Can you explain me the use of unless, to, so that, wish, would rather, and had better?
Please I need it for a homework of grammar.

That's a lot of stuff to ask someone to explain at once. I'd do a Google search if I was you.
