Unconditioned Stimulus:

This is a stimulus that naturally triggers a response without any learning needed. For example, the pain from touching a hot stove is an unconditioned stimulus.

Negative Reinforcement:

This involves removing an aversive event or stimulus to increase the likelihood of a behavior happening again. For instance, turning off an annoying alarm clock (removing the aversive event) when you wake up on time (desired behavior).

Punishment:

This refers to adding an aversive event or taking away something desirable after a behavior occurs with the aim of decreasing that behavior. For example, getting grounded (adding an aversive event) for coming home past curfew (behavior).
