You could meet them there at gate only if you had a boarding pass, I don't think TSA would let you in there past the front without one. They could meet you out front, but like someone else said, theyd have to allow time for them to go through TSA and to their gate. So yes its possible to see them but only before TSA checkpoint. They would need to allow at least 45 min . to get back through. That airport is not the easiest one.
No. They will have to come thru tsa again.
