so tl;dr version for euron = daario is

1. daario is suspicious because when the three stormcrows captains are introduced to dany, he has very reserved body language, acts polite, and doesn't say or do much of anything. however, when he comes back later, he starts acting like a completely different person. his body language and manner of speech are more bold and loud. additionally, he has salt stains on his boots which seem to indicate that he's been on a ship recently. the idea here is that the original daario was killed along with the other two stormcrows captains, and whoever killed them replaced daario by taking his form and using his position of authority to get close to dany.

2. if you presume that daario is suspicious you have to then wonder who he actually is. one indicator that it could be euron is the fact that euron seems to know a lot about dany's movements. specifically, he knows a lot of information relating to her that a person would only know if they had been near dany up until a certain point in time. this means he was following, spying on, or even a person close to dany for some point during the story before he returned to the iron islands. I do not consider this proof that he IS daario, it's just proof that he was paying close attention to dany.

3. pyat pree and three warlocks leave qarth in pursuit of dany to exact revenge on her. euron captures 4 warlocks. we can assume these are the same warlocks. it's likely he learned about dany and about the different savior birthing prophecies that relate to her from the warlocks. we know this is probably why euron is interested in dany. he also knows information relating to her movements AFTER this point in time, which means that he did not just get information about what dany was doing from the warlocks. he heard about dany from the warlocks, but then he went to see for himself and either followed her around or got close to her somehow.

4. euron appears in the story sometime after daario would have left dany. daario returns to dany at some point after euron leaves the iron islands. there is a bit of confusion here because of the order of certain chapters, and the fact that travel times are not known concretely, but based on the information that euron has access to regarding dany's movements it must be true that he was near dany up until a certain point in time. and this is after daario leaves her.

basically it's possible but that doesn't mean it's likely

also we do have reason to believe daario is suspicious, and we know for certain that euron is interested in dany
