First, I am so sorry for the loss of your father. I know this is a difficult time for you and your family.
As for your obituary questions, you have the right idea in how you have planned to include everyone. I am copying what you wrote and making a few changes (using letters to indicate where names should be):
He was preceded in death by his parents A and B; his siblings, C, D, and E; his former wives, F (mother of his children “lll” and wife “hjkl”) and G.
He is survived by his wife H; his children I and J; his step-children K, L, and M; and his siblings N, O and P.
You can certainly just state the number of grandchildren and great-grandchildren. You do not need to name them.
I hope this helps – we wish you peace and comfort in the days ahead as you get through this trying time.
