Yes. Realize that charges can either be POSITIVE or NEGATIVE. From Coulomb's Law\[F = k_e {q_1 q_2 \over r^2}\]So, if \(q_1\) is positive and \(q_2\) is negative the Force will be negative, meaning the charges will repel each other.

No worries. Magnetism is something that even escapes me at times.

Coulomb force is a vector quantity,and if you give negative sign then that means one charge will be negative of them .therefore both charge will attract to each other .and if you take it positive that means these two charges will repel to each other.and keep this two thing in your mind and give the vector form this force. if you want to calculate only the magnitude of this force then you should not mind the sign of charge because the magnitude always greater than or equal to zero.

yes we can and it all depends on the charges.
