You can not sponsor your mother for an immigrant visa until you become a US Citizen, however you can sponsor your mother for a temporary visitor visa depending on your income and family size.

No. Green Card holders cannot file immigrant petition for their mother.

You need to get your citizenship. You can apply in another half year.

Yes, but if will take longer than wait another year, apply for naturalization and after naturalizing petition for your mother as immediate relative.

You must first become a U.S. citizen in order to petition your mother for a green card.

You can only sponsor a parent when you become a US citizen.

There is no visa category through which a Permanent Resident may petition for a parent to get a "Green Card." If you attained your Permanent Resident status nearly four years ago by virtue of marriage to a U.S. citizen, then you already may be eligible to petition to become a naturalized U.S. citizen, and upon completion of that process you would be able to apply for your parents in the Immediate Relative visa category. If you attained your Permanent Resident status through another process, then you will need to wait until 90 days before completion of the fifth year of that status before you will be able to petition for naturalization.

How many years you have been living in US is irrelevant here. and unfortunately you can't sponsor her. You can invite her over for a visit on B1/B2 visa though.

No, as only U.S. citizens can "sponsor" their parents for an immigrant visa. As a permanent resident, you could execute an I-134 Affidavit of Support in favor of your mother to assist her in processing an application for a nonimmigrant visitor's visa, but there are no assurances that she could secure a nonimmigrant visitor's visa if she has a son or daughter in the U.S. who would soon be in a position to sponsor her for an immigrant visa.
