how much fluid are you supposed to allow out of the radiator when you bleed it? I know they say you should only let out the air then do it up again but there doesn't seem to be any air escaping, just a stream of water.

Start at the highest radiator in the house and work your way down.If you get a stream of water that radiator is OK.

If you have a radiator that does not get warm at the top it is most likely to have air in it. When you open up the valve you will hear hissing. Allow this to come to an end at which point some water will drip out. Close the valve immediately. If more than one raditator is affected make sure you manually top up the water in the system if this does not happen automatically.

Start at the radiator closest to the boiler...the air in the system rises. If you start at the highest point first, air trapped in the lower radiators will move to the higher ones. Once you get a stream of water, you are done.

once the water is passing through the bleed nipple should indicate that no more air is in that section.
as mentioned earlier, you will need to work around the whole house as the air gap may be locked elsewhere blocking the passage of the hot water.
your header tank - if you have one, is like a toilet cistern which has a ball vavlve in it which constantly maintains the level of water to feed the rads.
just make sure also that the valve at the base of the rad is also open and not turned closed. there should be a small arrow to indicate direction

You should hear a hissing, which is the air escaping. Some water will come out - it is forced out by the escaping air.

I allow at least a half of a coffee can of water to come through the lines before I turn them off.

The best advice is to replace the manual bleed with automatic float type air vents. They do the bleeding automatically.

why bleed the radiator? radiators in model cars are sealed systems and should be serviced by qualified technicians
