How about making pasta?

1. Well, with your help, I can do that.
2. Well, if you help me, I can do that.
(Are both the same?)

3. With your help, I could do that.
4. If you helped me, I could do that.
(Are both the same?)

5. With your help, I could have done that.
6. If you had helped me, I could have done that.
(Are both the same?)

7. Always be honest.
8. Be always honest.
9. Be honest always.
(Which one is grammatical?)

Yes, each pair means the same thing, 1 & 2, 3 & 4, etc. Seven, eight and nine are all correct grammar. #8 is a bit stiff or awkward, but is correct. #7 is how we would most likely say it.
