It's quite hard to say as every baby is different. Naps can vary, maybe 2, 3 or 4 depending on your baby.
As for feeding at night it is the same. Some babies may be still waking up every 2-3 hours, others may be sleeping for longer. Both are normal
I can't remember clearly but around 5 months my son was having around 3 naps and waking up about 3 times during the night for milk. You'll find other babies will have different routines
My son is only 4 months but just wan to say that research says its gd to delay solid food until 6 months old. Before that, most babies' guts are still immature. Give more breastmilk to protect your baby from getting sick
