What size drill bit is required to install these?

you need 10mm for wood drill (even if they say 9mm), depth 13/14mm. To put the ferrule you need Allen key probably 6.5mm (much bigger than the allen key provided)

What length is the barrel on these sash stops? i.e. the brass barrel that protrudes once fitted.

It protrudes 20mm and have a diameter of 15mm. It is screwed into the fitting in the window using an Allen key

How are these installed? Will they fit into a plastic frame?

Not suitable for plastic frames.

I drill the hole in the frame, then how do i screw it in? Or do i hammer the screw in?

If I recall correctly you screw in the treaded receiver using an suitable Allan key that slots into it.
