1. how to spawn monsters in the daytime so that they don't burn?
2. How do I spawn the amount I need and if possible in groups?
3. How to create monsters at night more than during the day ?

Now, whatever I try, it doesn't work. What am I doing wrong?

1. To make them not burn you have two options: equip a helmet or install another mod to prevents zombies from burning
2. Your amount line is already spawning them in groups
3. You can add a rule to spawn.json to randomly deny zombies at daytime by using "random" and "mintime"/"maxtime"

What do you mean by 'it doesn't work'? There are so many ways something doesn't work. So I need more info (also version)

Version 1.20.1 (forge 47.3.5). For example, the number of zombies does not change in any way. Zombies don't appear during the day

Are you reloading the world or rules? Are you killing everything after doing that?

Yes, I'm completely rebooting the game and making a new world.
For example:

P.S. (Here I made a night and abruptly a day for the zombies to appear)

Config:

[
{
"mob": "minecraft:zombie",
"persecond": 0.5,
"attempts": 20,
"amount": {
"minimum": 100,
"maximum": 300,
"groupdistance": 10
},
"conditions": {
"dimension": "minecraft:overworld",
"mindist": 5,
"maxdist": 20,
"minheight": 15,
"maxheight": 200,
"maxthis": 3000
}
}
]

Either I made a mistake somewhere, or something is wrong. It feels like the minimum and maximum number of zombies didn't work here

What kind of world is that? What height is the floor?

What kind of world is that? What height is the floor?

super-flat. Height of 4 blocks. Setting min height and max height does not affect anything. For example:

  "minheight": 1,
  "maxheight": 200,

If it's correct, then it doesn't work

Default superflat world is at -60 height
