yes and no. you'd have to project as Hell does not exist in the physical.
but i dont see the point. if your family member committed suicide, you'll just see them, along with the rest of the suicides in a bit of a coma like state. they'll only wake up when they themselves have forgiven themselves. plus, you'd have to spend a bit of time burning off your own karma that you've gained throughout life at the gates.
if you're going to attempt a visit to Hell, i suggest you go there as a chance to learn something new :) not to dig up the past.
