is there water in the oil, and now sign of damage on the head by an engine machinist, it might have a hairline crack in the block
Yes it can. A faulty thermostat can cause overheating which will cause coolant to be pushed out of the system.
Yes, low coolant can cause a loss of heat in the cabin.
No.
Bad thermostat, plugged or damaged radiator, loss of coolant, ignition timing is off, faulty water pump, head gasket... and who knows what other problems can cause overheating.
If by water you mean engine coolant, yes. Loss of coolant, antifreeze, is a major cause of overheating.

The engine has lost its coolant If it oer heated at the same time or it had a serious internal failure to cause the coolant loss it is ruined.
No. Excessive pressure will not cause the water to boil off quickley. It will cause the radiaor hose or other components to burst causing loss of coolant. A bad radiator cap can cause high or low pressure; low pressure will cause the coolant to boil at a lower temperature.
Fungi.
A LOCA is a loss of coolant accident. A rupture in the main coolant system resulting in a major leak of that coolant is a loss of coolant accident, or LOCA.
A loss of engine coolant can be caused by several factors, including leaks in the cooling system, such as damaged hoses, a faulty radiator, or a failing water pump. Additionally, a blown head gasket can allow coolant to escape into the engine or exhaust system. Evaporation can also occur in older systems with inadequate seals. Regular maintenance and inspections can help identify and prevent coolant loss.
change your antifreeze fill cap.
