What I got:

5. a. Br2 and H3O+. Then a Gilman reagent of (PhCHCHCH2)2CuLi followed by THF.

5. b. First Br2 w/ hv. Then t-BuO- and finally HBR with ROOR.

5. c. CH3O- and HCl (two step), rearrangement, more CH3O- / HCl and then intramolecular reaction.

Just some remarks

1)may be a michael's addition?

2)You would probably have the attack on the carbonyl ketone, which is added later to prevent self-condensation reactions.
