Is my Axiom EP-125 8" sub good enough for my 13 by 22 room?Should I add another? If so what will this do?
Will both subs work with my M22ti?

Your room is certainly large enough to justify another sub-woofer. The other side of this equation is how much power you have going to the M22s? If it is over 80 watts in this size room, assuming the room has normal characteristics, then another sub would be good.

I have a Harman Kardon AVR55 runing them at 65 watts per speaker but it is high current.Is it good enough?
Could i put a sub in each cornor of my room (13 feet)from ither sub?Do i need a power amp?

The high current will definitely increase your usable power. Placement in each corner should be very good. You can simply run an RCA cable from the HK to each sub using a Y connector or from the HK to one sub and then over to the other sub.
