How do I tell the difference between 'pa' to make things negative and 'pa' to make pronouns possessive?

Frame of reference, ... context.

Here are a couple of sentences.  Can you tell which "pa" is negative and which is possessive?

1. Mwen pa malad.
2. Nou kouri  san nou pa bouke.
3. Si ou kontinye anniye m, mwen pa prale nan sinema ak ou.
4. Eske valiz sa a se pa ou?
5. Ayiti se peyi pa m. M'ap toujou sonje li nenpòt kote mwen ye.
