Marking the enemy's ally as co-belligerent

[byebytoad]

If I mark one of the enemy ally as co-belligerent:
1-Can I still make separate peace with the 2 of them? (ie attacking Ottoman with Tunis as co-belligerent, can I make peace with Tunis first and then with the Ottoman?)
2-In case I can make separate peace with them, will I have to pay diplomatic cost when making territorial acquisitions against the co-belligerent?

You can always make separate peace with enemy allies called into the war (but not enemy vassals), whether or not they are marked as co-belligerents.

In general, if you do not mark an enemy ally as co-belligerent, that enemy will not be able to call in their own allies, but taking provinces from them will cost twice the diplomatic power.

1. Yes you can as ussual make a separate peace with Tunis
2. Im pretty sure you will have to(not sure tho), however warscore will be as if you take the province from the war leader

But be warned, calling an enemy's ally as a co-belligerent will make the enemy's ally's allies join in the war.

Afaik it's not the diplo power cost, but the war score cost.

Yes, it's war score cost. The primary benefit of declaring a country a co-belligerent is that is allows you to take lots of land from them. Especially useful in early game when you target large OPM alliances.
