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
