As a non-chemistry person, I assume the red diamonds are to ensure I don't put this in my mouth?
The first is a standard warning symbol, telling you to read the warnings.
The middle looks to imply that it's harmful to aquatic life; so no flushing, (upside-down fish and a piece of coral)
Third one seems to be dosage frequency, but saying a symbol isn't available. (QHS = taken every night)
At least make sure the thing you post is correct for something like this, as it can be important.
The first one (exclamation mark) means it is a irritant and the second one means it is hazardous to the environment (not just aquatic)
Even the third one is different than what they guessed, it's no GHS symbol, which means that even though there is a diamond, there are no further GHS symbols. Presumably, this is because of using the same packaging for many products. I wonder why they posted if they got 3/3 partially to completely incorrect.

The exclamation can mean that it's an irritant. It could also be other potential health concerns.
Try not to be too quick when trying to correct someone next time, especially when you are only half right
Cool. I learned something. Thanks!
Coral? I always assumed that was a tree and it means "hazardous to the environment"
The third one is "no GHS symbol", GHS being the Globally Harmonized System of Classification and Labelling of Chemicals.
To translate the sibling, the third one is where it would tell you how dangerous the substance is for you. But it's keeping its secrets.
