In the physics equation F=qE, where E is the electric field, q is the charge, and F is the force that the electric field exerts on this charge, does the charge, q, by itself have a direction associated with it? Why or why not?

No, charge is a scalar value. Such as 4.66E-11 coulombs. The sign associated with the charge indicates the nature of the charge + or -.
The same applies to current, it has direction, but it is a scalar.
