All bonuses are level IV.  The first is the Sidekick.  There doesn't appear to be any way to adjust their appearance, but you can choose them based on weapon skill (they seem to use weapon combos and movement powers, no class powers).  They last for a minute and the recharge seems to be 3 minutes (haven't timed the recharge fully).  It will heal you, regen your power and fight for you.

The next item is the Orbital Strike IV.  It damages all nearby enemies (direct then DoT), knocks them down and (iirc) debuffs them.

The last thing (the globes that drop) is the Supply Drop IV.  It has an initial heal then big regen for health and power as well as cleanse

Each of these items is a trinket that you trigger.  The higher the level, the more it does (ex: Orbital Strike I only damages a single enemy, no AE, no knockdown, ect).
