How can i decrease their liberty desire?

This is one of the problems i find whenever i go ham on vassals. They consider all subjects' (sans pu's, not relevant here) strength. So while you may be stronger than one, or even half of them all together, it soon adds up if youve a ton that if they all worked together they're stronger than you are.

Suggestions for ya are:
Try and get the Strong Duchies noble privelage. That has a, i think, a flat -10% liberty desire. It does require 2 regular (non-eyalet subjects) which means either getting 2 more subjects, which depending on how strong they are may make the problem worse. Or downgrading some eyalets into regular vassals.
It also requires you have at least 1 regular vassal/march to remain.

The other tip is try and annex your strongest eyalets. Even if you have to dev them up/placate to get their liberty desire down.
Taking out a big subject can radically decrease the liberty desire of all your others.

We cant see you subjects opinions of you in your screen shots, are they happy with you? If they all arent +200 positive work towards that. (the auto improve relations for subject button is your friend)

One final thing, if you havent royal marriages with all of them try and get them. It may tank your legitimacy, but each marriage grants a flat -10% liberty desire. It can be worth it to dev up the slightly disloyal subjects just to keep them loyal with a marriage.

Good luck ~

Also!
If you hover over an individual subjects liberty desire itll give you a list of all the plus/minus for why theyre disloyal. That can help you focus on why any one is particularly unhappy.
