The fixture manufacturer goes on the side of safety. A 75 watt bulb puts out both more light and heat than a 60 watt bulb. It can make the fixture burn out sooner. For even more light, why don't you go with a florescent and get a 27 watt bulb that gives off the same amount of light as a 100 watt bulb? That will give off far less heat and be far better for your fixture?
If the socket threads of the lamp are the same then yes the bulbs can be interchanged. The 5 watt bulb will glow brighter than the 4 watt bulb. If by a 4 watt light you mean a 4 watt fixture, then it is not recommended to place a larger wattage lamp in a fixture that is rated by the manufacturer at a specific operating wattage
The wattage of the UVB fixture for a beardie should be 26 watt bulb.
As long as the fixture in the confined space is approved for confined space and the wattage rating of the fixture is not below 60 watts then there should be no problem using a 60 watt bulb in this situation.
Technically speaking a bulb and a lamp are the same thing. You can use a 60 watt bulb in a fixture calling for a 40 watt bulb but I wouldn't. The lighting fixture may get to hot, melt and start a fire.
If the 250 watt bulb is a HID or similar type the ballast comes complete with the fixture. The bulb socket is also part of the fixture and comes pre-wired to the socket. To connect the bulb to the fixture all that has to be done is just screw it into the fixture's socket.

Look at the wattage capacity of the fixture. Some fixtures are limited to 65 watts, some can take much more. If you use a larger bulb than what the fixture was designed for you create a fire risk. If you need to use a larger bulb but the fixture is limited to 65 watts, you need to change the fixture.

The light bulb needs to match the ballast in the fixture.

Yes, the rating of the fixture is the maximum size bulb that the fixture should take. The fixture is rated to dissipate a certain amount of heat that is generated by a bulb. By putting in a bigger bulb and thereby generating more heat than the fixture was designed for, could destroy the fixture. Some fires have been known to start this way.
Light fittings should not be overloaded electrically because overheating can cause a fire. Alternatively you could use a 20 watt low-energy bulb.
No, the ballast's output is not matched to operate a fluorescent bulb.
No. Only replace lamps in a fixture that the manufacturer of the fixture recommends. By installing larger than recommended lamps this could create a fire due to the increase of heat generated by the over size lamp.
