Answer:
Logical fallacies are mistakes in drawing conclusions, or, let's say, drawing a conclusion that does not follow rules of logical deduction.
There is a great number of fallacies, but let us, in simple terms, define the ones given above.
Non-sequitur, as the name suggests, ("it does not follow") is a fallacy where the conclusion does not follow logically from the premises. It is sometimes used on purpose for a comedic effect.
Bandwagon is a logical fallacy which basically states that if majority of people believe or does something, then it must be true and, therefore, everyone should believe or do it. It can be observed in desicions mady by teens under "peer pressure".
False analogy (analogy meaning similarity) is a false presumption that when two concepts are similar in one characteristic, that must be true and for other, completely different characteristic.
Ad hominem is a fallacy most often seen in arguments. Instead of confronting arguments, people atack each other's characteristics and features.
So, to summarize:
1 - ad hominem
2 - non-sequitur
3 - bandwagon
4 - false analogy
