No.
Admittedly most Science Fiction stories are set in the future but they could be (and have been) set in all possible variations of the chronological scale.
Writers write what is interesting to them. Science fiction writers wonder - constantly wonder - about the universe. Is there life on other worlds or are we all alone? What would life be like if we had two suns? How would a culture evolve if the dinosaurs had not died off? What will people in the future be like? Science fiction stories are stories of "why?" and "what if?"Science fiction is the most important literature in the history of the world, because it's the history of ideas, the history of our civilization birthing itself. ...Science fiction is central to everything we've ever done, and people who make fun of science fiction writers don't know what they're talking about.Ray Bradbury
Ray Bradbury is commonly thought of as a 'Science Fiction' writer; this is not all though, because Bradbury describes himself as a "storyteller". He tells stories of every sort-- science fiction, fantasy, fiction, mystery....
Of course it can. Why couldn't it?It is the author's choice what point of view they will use to tell their story. Be it science fiction or any other genre makes no difference.An example of science fiction written in the first person is Margaret Atwood's The Handmaid's Tale.
No. Such stories are pure fiction and not good science at all.

Science Fiction is a subcategory of Fiction, meaning all Science Fiction is Fiction, but not all Fiction is Science Fiction.Science Fiction is typically futuristic, though not always, and sometimes involves space travel, time travel, alternate histories, new discoveries and technology, and/or alien lifeforms.
Alternate history is science fiction followed by a "what if" question, in a way that historical events were changed. One can find such stories all around the web.
It depends on the book or movie. Generally it does take place in the future because sci fi is all about aliens, timetravel, and technology.
Family stories, school stories, animal stories, mysteries, could all be included in realistic fiction.
Some would say that science fiction excludes fantasy but Arthur C. Clarke said, "Any significantly advanced technology is indistinguishable from magic. Science fiction authors have mixed science fiction with all other forms of literature. There are science fiction lyrics to songs, science fiction poetry, science fiction mixed with humor, science fiction mixed with westerns, science fiction mixed with romance.
The best science fiction stories have at their heart some scientific principle either illustrated or extrapolated upon. Such asMission of GravityNeutron StarThe Gods themselvesThe Moon MothIf I were to write a Science Fiction story I would first chose a principle and build a story around it.
