Yes generally normal for hairline cracks to form over time. Just use high quality caulk and fill it in. You can use a bit of water to make it easier to press into the cracks. Wipe off the excess before it dries. Then paint over with exterior paint
No, hairline cracks in stucco are not normal. The finish coat stretches. The lath underlayment secures everything from movement. It is cement, but not the same as a slab, walkway etc.
I was a plasterer for a decade or so before i left it to be a plumber.
Caulk is temporary at best here. Underlying issue, which is probably water ingress, needs addressed first IMO.
Water ingress is always the problem.
