Firstly you should know the relation or expression of Potential Energy...
Potential energy = K q1 x q2 / r where K is the Coulomb Constant and q1 and q2 are the charges and r is the distance of seperation betwenn them...
If You increase or decrease the magnitude of dissimilar charges keeping distance constant between them...Potential energy will Change...and if we change the distance between charges ( No matter whether charges are simillar or dissimilar) then potential energy will chnage too...
For instance , if you bring charges closer to each other , distance become smaller as a result Potential energy increases ( as distance r in the denominator )
One more thing about potential energy is that it is a scalar Quantity...but it carry sign...
