If I have part of a person credit card number, is it possible to figure out the rest. Are the first 4 digits of a credit card predictable in any way?

No, the first 4 digits of a credit card number are not predictable and cannot be used to figure out the rest of the number. Credit card numbers are generated through a algorithm and are therefore not predictable.
