Sleep advice

My son is 5 months and he goes to bed at around 7:30 and he’s wakes up on average about 7. Lately he has been waking up a few times at night, sometimes crying awake. He’s also been waking up around 6 for the day and today he woke up at 5 and won’t go back to sleep!

Is this normal? I feel like the waking in the night is somewhat normal but waking at 5-6 for the day is not normal.

He takes about 3-4 naps in the day and they range from 30-45 minutes. His wake time is 90 minutes to about 2 hours. We’ve been trying for 2 hours but I do go off his cues.
