Is it ok to stack new insullation on old one, in attic for double coverage?
Answers:
yes it's fine, no problems with that.
Other answers:
Not if the old insulation has a vapor barrier. If so it will cause condensation between the 2 layers.

i dont see why not my mothers house is all around double insulated and the heat stays in during the winter and the air in the summer but i guess it would be best to ask a proffessional where you live
definetely, But don't use new insulation with a paper back. Have fluff on both sides. The more the better and keep it away from the corner where the eaves are, you don't want to block them.
Good idea! Just be sure there's no insulation between the rafters. The attic space has to have ventilation or the roof structure will rot.
Yes.
By the way, with "In the Pink" fiberglass insulation and others, the vapor barrier went towards the living area. If that's what you have, be sure NOT to use additional insulation with a vapor barrier. Usa plain.
