Capacitors are primarily filters and can be made from many types of dielectric material. Meaning insulators basically. If by conduct you mean exchange electrons from one side to the other, then yes capacitors can "conduct" on both sides because AC current goes in both directions but for DC they don''t "conduct" at all!

@Curd is right. "fully charged" bears no meaning. Often, it just means that the capacitor voltage reached (of came very close to) the supply voltage. So, in this case, yes, you can fully charge it, at whatever voltage you want.

A capacitor can be charged without a resistor by directly connecting it to a DC voltage source.

This process will continue until the voltage across the capacitor equals the voltage of the source.
