Iam a fijian over stayer can I apply for green card

No... not only green card but you are not eligible to apply for any legal status in US.

Not enough information to answer your question. It depends on your visa and I-94 at entry, how long you overstayed, if you have otherwise violated the terms of the visa, and if you have a way to get peramanent residence. If employment based, then section 245(k) will allow up to 180 days. If family based, marriage to a USC, then section 245(a) will allow you to adjust to LPR status, no monetary penalty. It will forgive the overstay and unauthorized employment.

Hope this is helpful, good luck.
