What is an adjective for something that is not first but either second, third, fourth, etc? We don't need to know what position it is at; the only thing that matters is that it's not the first one.
EDIT: After reading the comments/answers, I realized I didn't provide much context. Let's say I have a few words preceded by a prefix. The first prefix however is different than the others, so we say there are different prefixes for the first word and the XXX (later) words. What can we use for XXX?
