What is the net force on the parachutist

That really depends.  Where is she ?  What's she doing ?

If she's sleeping, or watching TV, sitting in the airplane on the tarmac, or anything else where she's not moving, or if she IS moving but her speed and the direction of her motion aren't changing (like if she already bailed out a couple minutes ago and now she's falling at terminal velocity), then there's zero net force on her.

If she's driving to the airport along a curve in the road, or sitting in the airplane and it's taking off, or she just now jumped out of the airplane and she's falling faster and faster and faster, then there IS a net force on her.  But you gave us absolutely no information, so there's no way we can tell you how strong the net force is or in what direction it acts on her.
