I have seen the opposite done, so I'm sure it is "possible." In broad terms, you would need at least the transmission and associated computer, new shifter hardware and a new pedal assembly. You can probably review the online catalog at delorean.com to total the cost of parts new. Someone told me they thought it would cost them about $5K in parts alone to convert their automatic to a five-speed. I know someone with an automatic tranny and engine sitting in his garage. I think he only wants $3K for the whole thing, including the turbo, but everything needs work. As with all things cars, it probably comes down to how good you and your tools are... labor will really drive the cost up. Assuming you already own a DeLorean, even though I know it's easy to get attached to your particular car, you might consider cleaning up your five-speed, selling it, and buying a clean automatic. Given that the five-speeds are a little peppier, they probably command a higher price. Cost? Zero. You might even pocket some money.
Converting a manual transmission to automatic transmission is not possible but you can replace a manual transmission to an automativ transmission . That is also an expensive deal.
It can be done, but may not be the most feasible.

Yes
Yes, with enough money anything is possible.
Yes, it would be a lot of work, though.
Yes, you'd have to find the stock automatic transmission for your year and engine size, the stock automatic brake pedal assembly, and miscellaneous small things like transmission fluid, the transmission dipstick tube, linkages, etc.
If the Prelude is an automatic, yes, you use automatic transmission fluid. If it's a manual, there's manual transmission fluid. As much as possible, purchase the manufacturer (Honda) branded transmission fluid.
It isn't possible. You'll need to have the transmission rebuilt.
your cluch could be gone!
Why the hell would you want to?
Yes, by removing the manual transmission and installing an automatic. Unless you have a donor car this would be extremely expensive. My advice is that if you want an A/T sell the car you have and then buy one with an automatic.
