Zoro could react in a rather gruff way. He might say something like 'Nami, are you out of your mind?' But deep down, he might be secretly flattered. After all, Nami is an important person in his life. He'll probably need some time to process this unexpected turn of events and think about what it means for their relationship, both as nakama and potentially something more.
Luffy would be over the moon. He loves new adventures and a new baby on the ship would be like a new kind of adventure for him. He'd probably want to play with the baby all the time. Sanji would be a bit jealous at first because he has a crush on Nami, but then he'd also be really happy for them and cook all kinds of delicious food for the new mother and baby. Usopp would be making up all kinds of tall tales about the baby's future, like how the baby will be the greatest pirate ever.
The Wano Arc has indeed come to an end. It was a long and action-packed arc with many memorable moments and plot twists. The conclusion wrapped up various storylines and set the stage for new adventures.
