Yes they are correct, but you should change them a little bit. I usually help my sister do her homework. I usually help my sister to do her homework. I usually help my sister in doing her homework.

It depends on the rest of the sentence. *She needs help do her homework. -- This is not correct. She needs help to do her homework. She needs help doing her homework.
