If the petitioner's income is not enough to meet the affidavit of support requirements, then, yes, they he/she will need a co-sponsor for the affidavit of support.

I agree with my colleagues that you will require a co-sponsor. It does not matter where the co-sponsor lives as long as they live in the US and meet the poverty guidelines.

Yes he can be a sponsor. I'd have to confirm income/assets and poverty line guidlines to ensure you meet the treshold. But having a third party sponsor is not an incredibly unusual thing, it is allowed as long as the numbers make sense.
