in order:


 * Yes, this much is hinted at throughout the stages of Marineford. It is an astute and fair piece of speculation and can't be faulted.


 * Unfortunately not as shown when Akainu stormed his way through the Whitebeard alliance trying to chase down Luffy. The Commanders are certainly strong...perhaps enough so to take on a Shichibukai but the Admirals are an entirely different breed of animal all together. Heck one of them has a fruit that holds an order of superiority over two other Logia and can't be attacked by conventional weaponry as it disintegrates in close proximity to him.


 * I'd say yes to this, we know Marco and Jozu certainly can and Ace was offered a position as a Shichibukai so if not all of the commanders I'd say at least the top three take on Shichibukai and the others vice admirals.


 * Yes, this seems to be the case. Oars Jr. took on all of the Giant squad (atleast Vice admirals each) with no difficulty.
