I looked up ngrams, and saw the usage of "solve the confusions" is really low. But on the web there are plenty examples.

There are probably better ways to express your meaning than "solve the confusions".
Firstly, "confusion" is nearly always an uncountable noun, so it should be singular. If you feel that plural is more appropriate in your case, it might be because you actually should say "solve the problems". Many of the examples encountered on the web are from non-native speakers who really mean "solve the problems"
However if there really is "confusion", you might say "resolve the confusion", or perhaps "clear up the confusion" or even "eliminate the confusion"
