Ok Keith I'll try to make it simple. You are most likely to get good seeds by crossing lilies within the same group. Asiatic x asiatic, oriental x oriental and so on. As a generality asiatics and trumpets germinate immediate epigeal. Meaning they will put up a little blade of grass looking cotyledon at about 60-70 degrees and the true leaves will come soon after. Orientals will generally be delayed hypogeal germination. That means the seed will sprout underground and start building a small bulb at which point it will need a cold period of at least three months to send up it's first true leaf.
Regarding some of your crosses, I don't think you will get viable seed out of some. I believe that tiger babies is sterile and with wide crosses it is hard to get the seed to grow due to incompatibility and further steps are needed to achieve the hybrid. That said, anything is possible so don't let it stop you from trying.
