Can you take a Bonus Action when it's not your turn?
Scenario:
Monster action: Takes disengage action
Player with Sentinel and Great Weapon Master feats: Use their Reaction to take an opportunity attack and drops the monster. Can he then use a Bonus Action (assume the player hasn't used a Bonus Action since the start of their last turn) to make another attack with his Great Weapon Master feats on another monster in range?
No. A Reaction is the only "type of action" that can be taken outside your own turn. All normal Actions and Bonus Actions are for use on your turn only.
Here's a bit of a tack-on to this question... can a player use their action on their turn, but then ready their bonus action to trigger as a reaction later, or is it only Actions that can be readied for later?

The readying rules only ever say “action,” and readying a spell explicitly requires that the spell have a casting time of “one action,” so no bonus action spell can be readied. It seems pretty clear cut that you can’t ready any act that would require a bonus action.
Only an Action can be readied by taking the “Ready” Action.
Ready: Sometimes you want to get the jump on a foe or wait for a particular circum stance before you act. To do so, you can take the Ready action on your turn so that you can act later in the round using your reaction.
First, you decide what perceivable circumstance will trigger your reaction. Then, you choose the action you will take in response to that trigger, or you choose to move up to your speed in response to it. Examples include “If the cultist steps on the trapdoor, I'll pull the lever that opens it,” and “If the goblin steps next to me, I move away.”
When the trigger occurs, you can either take your reaction right after the trigger finishes or ignore the trigger. Remember that you can take only one reaction per round.
When you ready a spell, you cast it as normal but hold its energy, which you release with your reaction when the trigger occurs. To be readied, a spell must have a casting time of 1 action, and holding onto the spell's magic requires concentration (explained in chapter 10). If your concentration is broken, the spell dissipates without taking effect. For example, if you are concentrating on the web spell and ready magic missile, your web spell ends, and if you take damage before you release magic missile with your reaction, your concentration might be broken.

No, only Reactions can be taken on other people's turns.
