>I'm want to attach a female end to the circuit so I can just plug in the cable w/o cutting it up.

just cut the cable. you already have too many connectors in series with each other, and you want to add more. if you did, you'd have to source a female with the right dimensions, which you're prob gonna screw up, and then solder wires, which you're gonna screw up, and get the polarity right, which you have a 50-50 chance of screwing up.

if you really really value your cable, you might be able to find a power brick with a connector that fits in your battery, and sacrifice its cable.

>To connect the air pump to the circuit.

cut the cable! you might find a cigarette lighter extension cord at the dollar store (i did last time i visited) but most likely you'll have to wait another week or month to get it delivered.
(if you have a soldering iron, heat shrink and skillz, any cut cables can be restored good as new)

>To extend the pot on the circuit 2 meters. Will any similar cable size work

any wire will do

>Would these components achieve a similar effect, just with greater power loss?

yes, but it's not a good solution. besides power loss, the motor will have little torque at low speed. see pic.

> look up colleges near me and see if any staff members

a bit delusional. no college prof is gonna coddle some noob. maybe you can find some retired engineer/tech you will answer your questions while he caresses your hair.
