repository-pattern

I am new to DDD. In my mini-project, I have a structure that looks like this (different from the actual names):

EntryClassificationGroup
EntryClassification
Entry
EntryType

Should I have just one repository class for all these 4 entities, since they are all related? Or should I have individual repositories for each one?
