Person #1 -
Buddy I used to work on school projects with. He would sometimes be a hard-ass, trying to prove people wrong. He would be very glad when some work or project was done - like he becomes ecstatic after it was done, this would be quite J-like I suppose. Believes in never giving up. A somewhat nerdy guy when you see him - he's big into internet memes, programming, that sort of thing. Can be extremely herky-jerky when he's driving a car. Not an overly social person, but can talk a lot on subjects which interest him. He decorated his room a lot by making his bed a big fort. This was in sharp contrast to my room, which was... well... pretty plain.
Person #2 -
Probably the nicest person I've ever met. Loves to live life and is extremely optimistic (sometimes to a fault, where she will forget or ignore some responsibilities). Sometimes gets taken advantage of (because of her kindness), particularly by her husband. Actually took a cognitive function test, and she got ISFP (with Fi as her strongest and Se her 2nd strongest function, I believe), but she says she doesn't relate to that really. And I agree with her, there's no way she's introverted. ESFP, ESFJ are very possible. Not strict at all, very easy-going. If she has an opinion, she'll try to convince someone in a pretty mild manner. As long as the ones who are close to her are happy, she is generally happy. She can be persistent, but you won't get annoyed by it (has a mild way to do it).
Person #3 -
Friendly person, especially to people he doesn't know well, tries to make people feel comfortable. Lives on a farm, where he had to get up early to do work. He's pretty good with tools and fixing things and he's helpful. Drives pretty fast, loves playing Halo to the point where he plays it online almost 24/7. Sometimes can be easily annoyed, especially by people. Likes to talk about people behind their backs. Takes things lightly, knows how to turn something you say into a joke, he can be a really funny person, but knows when to take things seriously also. His room is fairly neat and organized - he usually knows where things are. Goes crazy at parties - gets absolutely shitfaced, and becomes the life of the party. Generally goes to bed on time (usually at midnight each night).
When in school, he always tries to find the easiest way to do something (and personally I don't blame him for this, although it will hurt him later). Like he uses homeworks from a friend who already took the class he's taking before, and he re-uses them. In other words, he's not a hard worker when it comes to school. Not the most intelligent student, but he can get by because of his resourcefulness, at least up to a point. Tries to get a lot of people involved in casual activities. From what I've seen, he seems to talk more when around more people.
What types would these people be?
