How many levels of magnification are there, how many follows, and roughly how many times is it magnified?

When RW1 slides to the right, op amp 1 in U1 is a follower. Op amp 2 in U1 is a follower. Op amp 1 in U2 is a follower. Op amp 2 in U2 is a follower. Op amp 4 in U2 is a follower.

Is it a follower as long as the output and input are short-circuited?

"As long as the output and input are short-circuited, is it a follower?" The output and inverting input must be short-circuited.

"Is it a follower as long as the output and input are short-circuited?" A resistor is connected in series between the output and the inverting input without a shunt, which is also a follower. At this time, there is no current on the resistor connected in series, so there is no voltage drop.

The original poster should first draw the circuit in a standardized way, according to the rules for drawing op amp circuits, especially for beginners.
