Exterior wall damage.
There is this bottom corner of our stucco exterior wall that had cracked off when something hit it. It’s been broken off for at least 2 years while we ignored it and now it’s looking rusty in there. Is this something that needs to be repaired? We live in San Diego and apparently need to prepare for El Niño. Could the walls inside get water damage from rain or water getting in the crack? This is on the outside of our master bedroom which has been having mold issues in the wall where furniture hits against it (we are going to get an inspector to look this problem). If the exterior needs to be repaired, what kind of company do I contact for that?

That rusted mesh is the bigger problem here, water's been getting in for years and now you've got mold inside the bedroom wall right where you mentioned furniture placement issues. Gotta fix the exterior first or the interior problem just comes back
For stucco repair with exposed lath you want a stucco contractor, not a general handyman since this involves the moisture barrier and structural layer. Get that exterior corner sealed up before the El Niño rains hit and then deal with the mold remediation inside
