For economical reason I want to insulate the ceiling and only cinder block walls necessary not to include 2 common walls.
What insulation materials to sound proof ceiling and to insulate the other 2 walls?? Can I do this by myself or enlist help?
Regular r-13 fiber in ceiling gives most economy. Then cover with 1/2" sheetrock.
Use 1 1/2" blue foam board on foundation walls, cover all exposed concrete, can spray foam for all joints except the bottom if you need drainage. Use verticle beads of foam construction glue and quick setting glue on 4 corners. 3/4" ply under the floor joist as fire stop, furring strips directly on insulation with tapcon, paperless sheetrock, then electric outside. That is way I did it. You can frame with metal or 2x for space to put the electrics, etc, inside the wall.
