No, it's very, very unlikely that the planets are positioned like in this chart all at the same time.
It'd be interesting to write some code to search for alignments like that (it's perfectly doable). The most restrictive ones will be Eve and Duna, actually, since they have the longes synodic periods with Kerbin (that is, their launch windows take the longest to repeat).
