The French Office for the Protection of Refugees and Stateless Persons (OFPRA in French)  can accept or reject your asylum application.

si votre demande est acceptée

If your request is accepted:

France recognizes that you need to be protected. You will be entitled to a residence permit (4 or 10 years). This residence permit is renewable. It allows you to stay on French territory and to work.

You can request that your parents, accompanied by your brothers and sisters under the age of 18, join you in France.
si votre demande est refusée

If your request is refused:

You can contest this decision before the National Court of Asylum (CNDA in French)  within 30 days. The court may overturn the decision and grant you protection, or uphold the rejection decision.

It is advisable to be assisted by a lawyer before the CNDA. You can ask the court for free legal aid within 15 days.
If you are no longer able to challenge the decision to reject your application, you can nevertheless request a reexamination  if events come to light that confirm your fears.
