use two 12 volt batteries in series.
you only need two 12 volt batteries to make 24 volt. connect them in series
Two 24 volt batteries in parallel will give you 24 volts. The only other way is two 12 volt batteries in series.
No, you will need two 12 volt batteries connected in series to give the 24 volts necessary to run the pump. It will not run on 12 volts.
No Yes. hook two in series, two in parallel.
No, but you can charge each one individually without separating them from the series loop.

You would need to connect the two 12 volt batteries in series. That will give you 24 volts and the amps of one of the batteries. Voltage doubles and amps stay the same.
Yes, if you wire them as two pairs in series to each other. Two batteries in series will give you 24 volts, and another two in series will give you also 24 volts. put the two 24v groups in parallel and you have 24 volts.
You will have 24 volts DC.
24 Volts.
