Co-pay: Term often used in health care, insurance covers part of the cost and you pay the rest. Seeing in this situation you are paying for the insurance itself, the term is not correct.
Deductible: An insurance term for when you have to pay a certain amount before insurance will cover the rest.
Premium: A fee payed by the insured (Jan) to be covered. This is my best guess for your answer.
Claim: A claim is when Jan would request the insurance company to reimburse her after a car accident (or her tires got slashed, etc.)

Resistors R1 and R2 are connected in series, whereas R3 and R4 are in parallel.
For the current it means that the current through R1 and R2 is always equal, which is not the case for R3 and R4, there the current splits depending on the R value.
For the voltage it means that the voltage over R3 and R4 is always the same, regardless of the R value.
