Baal is asking a LOT of the right questions you gotta ask yourself.
To simplify it all, you will get better at reading spin as you become a better player, and there is no way to achieve that overnight.
You will get better much quicker if you understand what is happening to the ball, know the clues, the possible responses, and be ready to do them. That sounds really simple, and it is in concept, but in application, it takes a heck of a lot of time and assistance with competent help near you often.
You must develop an ability to take a snapshot of the ball and bat at the moment of impact. You need to know the opponent's surface, the bat speed, the bat angle, and the swing plane at impact. After that, you got the placement of the first bounce, how the ball travels in the air, and how it bounces once it hits your side. After that, if you haven't figured it out, you are shooting in the dark.
These skills of recognizing it are only the beginning. There are many possible responses you can do based upon your opponent and your abilities. Confidence is also a huge factor. After it is all boiled down, it comes to how much you can rely on your skills, training, and experience. This holds true for most things in life. Sometimes luck is a factor, but skill and caution are numbers 1 and 2 in many things in life.
There are a ton of write-ups on how to receive serves and there are a thousand tons of vids for it. It is profitable to look at these and learn from them, but NOTHING replaces a competent individual SHOWING you what is going on, telling you what you can do, and placing you in the situations to do it and give you the right feedback and motivation. Usually, we call such an individual a COACH, but even in my own highly developed industrialized home nation, there are woefully few of these TRUE coaches.
I am along the lines of BAAL, I would rather tell you straight up what you are up against instead of baby sugar coat it.
