Question: Why do people in the film refer to replicants as androids and machines when (just like normal humans) they seem to be made of flesh and blood and are not mechanical?
Answer: The replicants are indeed androids/machines; like Terminators, they are made to look human by adding human parts, such as skin and blood and even organs ("surrounded by living tissue", if you will). Unlike Terminators, however, they are not programmed simply to kill/destroy humans...they are simply "upgraded" versions of humans, who like all of us want to live with freedom and self-actualisation.
Question: I'm aware that there is debate on whether or not Deckard was a replicant, but as I was watching the movie, I couldn't see any clues as to why anybody would think this. Did I miss something obvious? Why do people think this?
Answer: The two most notable hints are as follows. The first (which is only in the Director's Cut) is that after Deckard dreams of a unicorn, Graf makes an origami unicorn and leaves it at Deckard's apartment. Some people interpret this as suggesting that they're aware of the memories that have been given to Deckard to prevent him realising his true nature. The second hint is that replicant eyes glow in certain lights - at one point in the film, Deckard's eyes can be seen glowing in the same fashion. Ridley Scott has stated on several occasions that, as far as he's concerned, Deckard is a replicant, but he does concede that they deliberately left it as somewhat ambiguous - the viewer should decide for themselves.
Answer: Rachel asks Decker at one point if he had ever taken the replicant test himself, and he doesn't answer. Even though the movie itself doesn't seem to stress the point, in the book on which the movie is based "Do androids Dream of Electric Sheep?", the question of whether the protagonist detective is an android is the main theme.
Question: I read that, during the filming, Harrison Ford and Sean Young strongly disliked each other. What was the cause of their feud?
Answer: Mostly it was personality clashes between Ford, Young, and also director Ridley Scott. Ford is not particularly congenial or talkative, and tended to be put off by Young's more hyper, off-beat personality. Young claims Scott wanted to date her, but she refused, and said he then treated her badly. Ford and Scott also had conflicts.

This is an answer for the wrong film.
Question: Why had the replicants tried to break into Tyrell Corporation? How come Roy Batty knew the corporation existed at all?
Answer: Replicants appear to know about their origin and lifespan, and even if they didn't, Roy is highly intelligent and motivated, and could easily have determined Tyrell's role in his creation through various means. The reason they broke into Tyrell Corp was they wanted the company or Tyrell himself to extend their lifespans, or to work out the means to do it themselves.
Answer: This could start getting metaphysical but ultimately it's semantics. An android is a humanoid robot. A robot is "a machine capable of carrying out a complex series of actions automatically". A machine is "a physical system using power to apply forces and control movement to perform an action". Note none of those definitions specify metal parts, or even being artificial. Human beings are machines, in the same way that human beings are animals, in literal terms, we're "just" biological machines, but we tend not to think of ourselves as such, because "human" is a more specific definition, and people like to feel that humanity confers a higher status of sorts. So it boils down to us vs. them, really - despite all of their many human traits, a lot of humans don't want to be conflated with replicants, so different terminology is used. There's also an argument to be made that as with a lot of dehumanising terms used in the present day, calling them machines helps to justify mistreatment, even though the replicants are just as capable of life and thought as humans are.
