Then is it possible for those 8 batteries to be charge will a charge that has an output of 8.4volt, 2Amp current?
I'm not sure what you're asking as your sentence structure is a bit broken, but if you're asking can you charge them, no, 1.5v AA cells are non rechargeable and any attempt to do so will result in a potential fire.
If you simply meant how much charge can you get from them, I'm not sure. It would highly depend on the battery, most are not the same as each other. One AA battery might give 1C just fine, whereas another of the same capacity might only be okay to use at 0.2C due to internal resistances.
To get an answer, look up the datasheet for the specific battery (brand and model) you wish to use.
At an educated guess, I would personally believe that setup should work fine (just remember a Pi only wants 5 - 5.25v)
