How many days do these sidequests require time to do them?

[Hochmeister]

Ok, I kind of messed this up. I have tomorrow Kuttenberg tournament and I thought, that the Ransom will be quick to be done after I negotiated the ransom, but it seems to be that I will need another one or two days based on what happens next (and I must do stuff next day in this quest). And during "the Ransom" I (not willingly) opened Spoils of war, and I got just three days ( I don't know if the day, when I opened this quest does count to countdown), well I guess I definitely shouldn't go for "Taking French leave" in the current situation. And there is side quest Spark (not opened yet). Ah dammit I will have to reload the safe...

So to sumarise this:

1) Kuttenberg Tournament, Spoils of war, Ransom, Spark - How many days do these sidequests require time to do them?

2) kind of curious - does doing any of above mentioned sidequests influence before certain main quests, maybe some dialogue in "King's gambit"?

3) little bit of topic question, I know there is another task from Cimburk brothers, my question is, will they stay in ruin of castle Cimburk after this another task is done? I still want to learn some combos from Balšán Cimburk.

and technical question for this quest do I need to have finished or not to finished some of those above mentioned quests or tasks? Because of the option of call some people connected to those quests as reinforcement and risk of them dieing ( ----) canceling some quests)

And second question: I heard that there is option to call Mikesh and Kozliek; and some Emmeram and Linhart as reinforcement too, but I don't have this option, only those not mentioned above - Kubenka and Komar, Cimburk brothers, Arne, Mercenaries. So for duos Emmeram and Linhart; and Mikesh and Kozliek as help option, what needs to be done?
