3. Yes, it is a fallacy. Even if it looks old, it might not be over 100. It could be 50, 60 or somewhat around that.
4. This is also a fallacy. When clouds are presented, it doesn't mean it is going to rain. Maybe the clouds are low and white - meaning the weather is OK. It only will rain (and by that i mean not 100%) when the clouds are grey and dark.
5. This probably depends whether the buyers are actually comfortable.
Because natural ingredients are pretty much balanced and healthy, but if the customers do not like these ingredients and, for example, want alternatives, then it might turn out to also be a fallacy.
My opinion is that all of them are fallacies (if any of them doesn't make sense just tell me)
