What about Okura is released and combine fears ? If i combine fears in a unit, can I, as an interrupt, play Okura is Released to destroy the card I just bowed ? Would that be considers interrupting an interrupt ? If not, why ?

If the initial Fear comes from a Battle action, you can play as many Interrupts to it as you like, being Okura is Released and/or any other Fear abilities in the unit used to combine with it.
The problem in the link you cite is that the INITIAL Fear is an Interrupt, so NO Interrupts can be taken to it.
But most Fears are Battle actions, which can be freely Interrupted, with as many and as many different kinds as apply.
I hope that clears things up.
