Hi there! Is it possible to remove signal below a defined power-threshold? For example all signals below the power of 5.

Do you want to remove a signal if ALL of the elements are below 5? Or if the MEAN or median of all the elements is below 5?

It depends on what do you mean by "remove." If you just don't want to skip those frequency values than do something like this
f = [f1 f2 f3 ..]; % vector of frequency values
s = [s1 s2 s3 ..]; % vector of power signal
mask = s > 5; % find the signal values greater than 5
plot(f(mask), s(mask));
For a specific solution for your signals, please share details of how the signal is stored or share the signals in a mat file.
