This question is linked to deactivation of lifetime events on participatns in sequence diagrams.
As far I see, the lifetime events are deactivated in the "Last in, First out " fashion, but I would like to deactivate them whenever I want. Is there a way to do it?

I think I don't fully understand your question. You can have this :

@startuml
participant Foo1
participant Foo2
Foo1 -> Foo2 : msg 1
activate Foo1
Foo1 -> Foo2 : msg 2
activate Foo2
Foo1 -> Foo2 : msg 3
deactivate Foo1
Foo1 -> Foo2 : msg 4
deactivate Foo2
@enduml

You can also choose to deactivate Foo1 before Foo2. But I guess this is not what you are talking about.

Unfortunately you haven't understood want I'm aiming for.  
At the moment, if several lifetime events are active at the same time on the same participant (your answer is for different participants), I can deactivate them in a Last In First Out fashion, but I want for example to deactivate first the another event, not the last one activated.

I would like to request this as well...

Here is what we can only do:

and this is what I would like to achieve:

-------------------
a->B ++: call ( )
B->B ++:
B-->a --: return
note over B: do some stuff
return
-------------------

Maybe I would suggest an improvement on "return" keyword.
Something like: "return" would be the same as "return(1)" and if you set "return(x)" it it make the previous "x" call to return. [in this diagram would be return(2)]
