Yes. The voltage is the same on each. The ma rating of the power supply is the current the supply can handle before burning up. So if your appliance is designed to work on an 800ma supply, an 850ma supply will do fine.
Yes you can. But it may damage your computers power supply.
all about regulated power supply
If it is a computer power supply it is the box that gives the computer its power from the outlet.
In an ideal DC power supply, there is no ripple.

Output is: DC10V - 800mA - Center Positive
Yes you can. But it may damage your computers power supply.
Generally, yes. If your devise will only draw 80mA, it will do it whether it is connected to a supply that is capable of supplying 300mA or 800mA. The amperage rating on the power supply is the highest current that it is rated for. It will easily and safely provide less current. The load that is connected to the power supply will determine the actual amount of current.
For power supplies, if the voltage is the same, the rated amperage is equal to or greater than the requirements of the device, and the plug fits, the supply is safe to use.
No. A device that requires 2100 ma or 2.1 amps can not receive enough amperage from a power supply that will only deliver 850 ma or .85 amps.

When sizing power sources, you must match voltage (which you have done) and make sure the supply can supply enough current to the electronics. If your supply is the 800mA, and the equipment using this needs 2500mA, then the power supply is undersized. If the supply is the 2500mA and the user is 800mA, then your power supply is oversized, and will work just fine.
No because they have different connectors.
Yes. There's a subtle difference in the meaning of the "--- ma" labels on the two units:-- On the "device" ... the unit that uses power ... the "200ma" is the current it useswhile it's operating.-- On the "adapter" ... the unit that supplies power ... the "800ma" is the maximumcurrent that it's able to supply. Anything less than that is easy.So your adapter is OK to operate your device. In fact, with suitable wiring and a bit ofcooling, it could nominally operate 4 of them at the same time.
The output voltage available at a USB port is controlled by the regulator in the computers power supply. It is fixed, you can not change or control it. The maximum current which should be drawn from a USB2 port is 500mA, from a USB3 port it can (I believe) be up to 850mA.
It is usually safe to use lower amperage on appliances, however, unlikely that it will have enough power to operate let alone power on.
