Hello, my friend, welcome to the poker world!
This question is very good, but it doesn't have a unique answer, unfortunately...
To know the correct spot to use each hand in poker you need to keep studying a lot of things...
I'm not a poker pro, but I can simplify for you what you need to understand first.
The correct way to play our hands depends on some specific things, like: hero's position (your position), villain's position (opponents position), how many villain's are you playing against, game type (tournament, sit n' go, cash game, etc.), ICM (if you are playing a tournament or a sit n' go, for example; ICM means Idependent Chip Model and it's like another way to see the value of your chips, but this is more advanced), your stack amount, your infos about villain(s), villain's infos about you, and a lot of other things you could search for.
I know it may looks too much things to learn, but you will start to get it soon or later.
Good luck!
