This is a voltage drop question. A voltage and whether it is a single or three phase system must be provided to give an answer.
It depends on what the amperage of the motor is. The motors amperage depends on the voltage of the motor. The higher the voltage the motor operates on the lower the amperage. So unless the amperage from the motor's nameplate is stated an answer can not be given.Just remember that the feeder capacity to the motor has to be 125% of the motors full load amperage and the breaker protecting the conductors to the motor has to be rated at 250% of the motors FLA. This higher breaker size allows the motor to start without tripping a normal size breaker that is rated for the lower conductor size.
In standard construction this would require a 15 amp breaker and 14 gauge copper wire.
A 30 amp circuit breaker is needed unless the load is a motor circuit, then it has to be sized to 250 percent of the motors full load amps. For 30A circuit is needed breaker 30*1.25=37.5 --> 40A. If load is lamp or heater, then use breaker of group A or B. If load is motor, then use breaker of groupC or D (very hard start) or special safe breaker for motor - with variable amp setpoint. See related link also. By code you are only allowed 80% of the rating of a breaker. So 30x80%=24amps. 24 amps is the MAX allowed on a 30 amp breaker. You would need a 40amp breaker for a 30 amp circuit. 40x80%=32. So you would want a double pole 40amp breaker.
If there is a possibility of both operating simultaneously, then a 100 amp breaker (actually 80 amp if you can find one), and appropriate wiring would be required. Even if they were not expected to operate simultaneously, it would be prudent to wire as if they were.
A dryer requires a 30 amp receptacle. This will be to receive a four blade dryer plug. The wire needed will be a three copper wire #10 cable set with a bare #14 copper ground wire. The breaker will be a two pole 30 amp breaker.

It's possible to run 2500 feet of underground cable between two 200A breaker boxes, but there may be some power loss due to the resistance of the cable over that distance. To minimize power loss, it's important to use a cable with appropriate gauge size for the distance and amperage needed. Consulting with a qualified electrician to determine the best cable type and gauge for your specific situation is recommended.

A minimum of 15-amp breaker is "needed", but a 20-amp is often required by electrical code for that situation.
It depends on the total load spread along the line and the voltage drop at full load at the end of the line. Generally up to 3 % voltage drop is considered ok. Anything beyond you need another transformer center.
A 30 amp breaker wired with AWG #10 wire.
The size of the breaker needed for a 220V wall heater depends on the current rating of the heater. Generally, for a 220V heater, a 20-amp breaker is common. However, it's important to check the manufacturer's specifications and local electrical codes for the appropriate breaker size.
This question is at cross purposes. A breaker is used to protect the conductor that is connected to it. With a distance being added into the question it turns it into a voltage drop question. Depending on what the amperage of the connected load is, a 40 amp breaker might protect the conductor. A voltage needs to be added to the question. Re-phase the question to include a voltage, and load current. For example, What size wire is needed at (voltage here) with a load amperage of (amperage here) over a distance of (distance here). Once the wire size is established then a breaker is chosen. It also helps to know what the load is, eg. motor, sub panel, transformer, because additional calculations need to be made.
Yes, it is recommended to keep both the AC breaker and furnace breaker on, especially during the respective seasons when they are in use. This ensures that the units are powered and can function properly when needed.
In standard construction this would require a 15 amp breaker and 14 gauge copper wire.
Normally AWG #10 wire on a 30 amp breaker but it really depends on the size of the pump. The pump manufacture will specify the size wire and size breaker needed.
The electric furnace operates on 240 volts so a two pole breaker is needed.
