You don't add refrigerant to the compressor . You add it to the low side suction line , not high side . Your best bet ,take it to a qualified repair shop.

What size is high pressure hose and suction hose for a 94 toyota 4X4 22RE 4 cylinder

I'm assuming you are asking about the air conditioning hoses. If you are trying to add refrigerant you need to put it in the suction hose. If you are using the cans from the auto parts store, it will only fit on the suction side of the system. They have tried to dummy-proof the connections so you don't blow the can up. The suction side will be the larger hose. Also, there will usually be insulation covering the hose and or lines. The refrigerant port is just above the compressor. If your system has leaked off, try a leak sealer with an indicator in it. You use a blacklight to find the leak. If you really want the leak fixed without tearing the system apart use Superseal. This stuff is so good that it seals up the hose that comes on the can. You can't re-use it.

"blew out" is a bit dramatic...If it's a pcv hose it should have a ton of suction at the open end or where it had been attached.Also with that hose detached, your engine won't run at idle very well or at all. Most often, any hose that becomes disconnected stays pretty close to where it's supposed to be attached. Simply look for a clean attachment nipple near where you found the hose and put it back there.

Coolant leak

without any more description than this can only guess as to where. The hose end can leak because it's not on properly,< loose, crooked , torn etc. Hose is attached to water pump and it can leak from seal around mounting point or the hole on bottom side of pulley shaft. If leak is from water pump then you should replace it,< to repair seal it has to be removed and putting a new one on is best to complete repair without possibly having it break you down soon after repairing seal>, if it is leaking from hole on pulley shaft it will have to be replaced.

The Freon goes into the "suction" hose/pipe assembly. There will be a service port on this hose. The low side (blue) hose of the manifold gauge set gets connected to this fitting. The suction hose can be identified by it's larger diameter (compared to the discharge and liquid hoses). The suction hose will run from the compressor across the top of the radiator (slightly behind the radiator), then back towards the firewall on the passenger's side of the engine compartment. The service port is generally closer to the firewall, than to the compressor.
