no... one will float on the other and at hi temperatures or hydryrolic pressure will foam or create dangerous pockets in required pressure.
The "Pour Point" of engine oil is about -44ºF.
Yes that's why antifreeze is used, these are the freezing points of some types of oil. Motor Oil (15W) +15 Motor Oil (30W) 0 Hydraulic Oil, Gear Lube & Gear Oil -10 Motor Oil (10W30) -20 2-Cycle Oil -25 Motor Oil (5W30) -30 Mobil 1 Engine Oil (15W50) -35 Antifreeze -40 Mobile 1 Engine Oil (15W30) -55

The cross reference for m-4864 which is a hydraulic oil or transmission fluid is SAE 80 for below freezing temperatures. B (SAE 90) is used for temperatures that are above freezing.
If it's not a lot there shouldn't be any problem. The two are not going to mix, the oil isn't going to affect anything in the system.
Change the head gasket.
Hydraulic fluid and hydraulic oil are one in the same.
This means that there is oil getting in your antifreeze. More than likely you have a blown head gasket. Stop driving this vehicle until you have this repaired.
hydraulic oil
emolliating hydraulic oil in the lowest part of the hydraulic system.
no but antifreeze in oil will eat the bearings
No, oil is lighter than antifreeze.
