Yes, as Chuck has said F2 refers only to the result of crossing F1 
individuals from the same initial cross. I don't believe there is any 
special terminology for the cross of two seedlings of related but not 
identical parentage.

F1 & subsequent generations.

Online definition says F2 is > The progeny of self-pollinated F1 
generation plants

But I've also heard/read F2 used this way:
> The F2 (second filial) generation consists of the offspring from allowing 
the F1 individuals to interbreed - the grandchildren of the parental 
generation.

So what do I call the offspring of two related F1 seedlings that are not 
siblings, but are part of my non-line breeding program?  i.e., crosses 
between half sibs, cousins, etc.

I was assuming that any 2nd generation away from the parental one was an 
F2, but looks like that's not the way F2 is normally used.
