It depends on the guitar. You really haven't included enough information in your question. For all we know it could be a high end Martin or one you got from Argos/Wal Mart etc.
Acoustic-electric guitars are acoustic styled guitars with a pickup either outside or inside the hollow body. You plug a cable into it like you would a normal electric guitar and it can be used through an amplifier to make the sound louder. They can also be played without being plugged in just like a normal acoustic guitar

Yes, you can plug an electric guitar into an acoustic amplifier. But I would suggest that you don't play at a high volume for a long period of time of the difference in impedence - an acoustic guitar (and bass and vocals) is low impedence, where an electric guitar (& keyboard) is high impedence.
Nylon Or steel are best for acoustic but i would recommend having nylon strings on classical guitar rather than acoustic.
For the same gauge designation, yes. "Standard" or "Regular" gauge acoustic strings are .013 to .056. Those would be considered very heavy strings on electric guitar, where "Standard" or "Regular" gauge strings would be .010 to .046.
An acoustic guitar produces sound via the "sound hole" cut out in the wood under the strings on the main part of the guitar. This is a nice acoustic sound. For a fuller, higher volume and amplitude sound, with the same acoustic-type sound one would would a semi-acoustic. This is an acoustic guitar that has the same kind of volume boost built in, as one would find on an electric guitar. It is important to note that the sound made with a semi-acoustic is still quite different from an electric guitar, even though one would need an amp to play the semi-acoustic.
I would just say let the acoustic guitar be, and buy a hollow-body electric guitar.

A good one would be around 200$, but if you just want one to play, look on craigslist and you'll probably find one for around 50-100$

You mean an electro acoustic (that's just what I call em but ya know)? That would be the pickup situated inside the body of the body of the guitar.

you could listen to it in Spain :)
There are many different types of guitars, some would have to be the 12-stringed guitar, the Mexican Jarana, the South American Charango, the metal-strung guitar, the Cello guitar, the Hawaiin guitar(Ukulele), the electric guitar, the acoustic guitar and the electric-acoustic guitar.
It will always sound like an acoustic guitar but the tone might b bad if u play it through an electric guitar amp. it would b better if u just buy an acoustic amp.
