If I understand your question the passage is speaking about Noah, his wife, and their three sons and their wives. And if I understand your reference as to soul keep in mind that these people were not dead. I know of no place where soul is used in regards to being dead or being resurrected. However like I said the terms soul, and spirit are not clearly defined in scripture so as being able to come to any kind of clear understanding as to what applies to them. If soul fits biblically when resurrection is used that is fine with me.
That is correct they were living souls. What does it take to make a living soul?

Everywhere that 5315 is translated body it is the word for soul. There is no reason to translate it body except for the belief that the soul can't die, yet the word of God says at least twice that the Soul (why not body) that sinneth it shall die.
