You can strum a guitar in various ways. You can strum with your thumb only, with your index finger (nail side strumming the strings), with your thumb and index (thumb supporting the index finger, simulation of holding a pick) and even with all your fingers. There are many ways of strumming the guitar, maybe some that I haven't mentioned here. It really depends on what the individual guitarist prefers though and what they find easiest
An electic guitar can use any pick, as a acoustic guitar can use. If you want to strum you want a flismy pick, or a small size. And if you want to pick the notes your going to want to have a hard pick, or a large.
You can strum, pick, even tap!
You can strum with the index fingernail and thumb; just put your index and thumb together and use the index on down-strokes, and the thumb on up-strokes. It works well if you roll your two fingers.
anywhere on the strings below the nut and below where your hands are on the neck
A classical guitar IS an acoustic guitar. Now, if you are asking, "How can I make a classical guitar sound like a steel-string flattop guitar", the answer is: You can't. The only way you could approach that is to put steel strings on the classical guitar, and if you do that, you WILL, not "maybe", FOR SURE, destroy the guitar. In fact, the bridge may pop completely off the guitar while you are tuning up for the first time. If you want steel-string sound, get a steel-string acoustic. Please don't ruin a perfectly good classical trying to get that sound. This is 45 years of being a guitarist talking, here.
you can strum with your hand, or do what they call fingerpickin' go to youtube and look for videos tha'll show you the techniques.
