Assuming you have a bench of some sort, a pull-up bar and a couple of sturdy plyo boxes you have the choice of...
Upper body pushing:
Push-ups (banded or weighted if you use a dip belt around the middle of your torso and elevate yourself on the plyo boxes+bench)
Dips (weighted, requires a couple of parallel bars)
DB flat/incline press
DB shoulder press
DB floor press
------- (more isolation type stuff) ------
DB lateral raises/upright rows (can be used with bands to provide more consistent tension through the range of motion)
DB around the worlds/circular flys
Floor slider/dual ab-wheel flys
All sorts of tricep isolation movements (lying extensions, overhead extensions, French press, Tate press etc)
Upper body pulling:
Chin/pull-ups
Inverted rows
Rack chins/pull ups (pull up bar plus bench)
DB rows
DB seal rows (bench + plyo boxes)
-------
All kinds of curl variations (incline curls, standing, concentration, spider, hammer, etc)
Face-pulls/bent over reverse flys (can used with bands...)
Lower body anterior dominant:
DB goblet squat on plyo boxes
DB belt squat on plyo boxes
DB rear foot elevated split squat
DB split squat
DB step-up (onto box/bench)
DB wall squat (w/exercise ball)
DB cossack squat/lateral lunges
DB single leg box squat
DB lunges/reverse lunges
----------
DB lying leg extensions (on bench/boxes)
Pistol/shrimp/sissy squats (bodyweight)
Zombie leg extensions (bodyweight)
Lower body posterior dominant:
DB RDL/single leg RDL
DB Good Mornings
DB deadlift (DBs would need to be elevated off floor slightly)
DB hip-thrust (on bench)/glute bridge also single legged versions
DB seated good morning
------------
DB hamstring curls (hang off pull-up bar)
Gliding leg curls (requires carpet slider things or an exercise ball)
Nordic curls (needs pad for knees and some way of locking your feet)
DB frog pumps
DB single leg calf raises (seated, standing, w/front of feet elevated slightly)
Then obviously there's a million things for core. You'd have to build up a collection of dumbbells and fractional plates (magnetic ideally) to be able to progressively overload in sensible increments for many of these.
