Well, firstly, inductive reasoning is reaching a conclusion based off of a series of observations. An example is if you noticed that all the pigeons you see are grey and so you make the conclusion that all pigeons are grey. It's a conclusion based off just a few observations, not necessarily true or false.
Based on that reasoning, I'd say 1 and 4 are inductive reasoning. 2 is deductive reasoning because it's based on a fact, as is 3.
