Assume the left most charge is the test charge rated at 1c

If the electric field lines are behaving like that, the two charges have the same sign. Hence if you know the left most charge is positive, the right most must be also. If the electric charges had opposite signs, there would be electric field lines running between the charges.

If I don't know the charge of either can I tell if it is or not?

No, they could be both positive or both negative.
