First off I am new here so HOWDY !! I am a pedal addict and have bought , sold , traded still own to many pedals to count especially OD/Dist boxes . I would recommend ....
Delay: Wampler faux echo ...had mine for a couple months it kills
Tremolo: Fulltone supatrem , cool trick-works well as an always on boost as well
Octave: OC 2
Chorus: TC SCF or TC Corona Chorus
Overdrive/boost: For Something fat but with the ability of higher gain I highly suggest Fulltone Plimsoul , it covers a lot of ground .
Other boxes I am recently in love with and recommend Xotic EP boost , AC Boost and SL Comp , Prescription Electronics Vibe , Dunlop Bonamassa wah , RMC Picture wah
