Creole originally referred to people born in colonies of French or Spanish settlers, distinguishing them from European-born residents. Hellenic relates to Greek culture. Celtic refers to Celtic peoples (Irish, Scottish, etc.). Scandinavian refers to Nordic peoples - none match the definition.

L₁ would be accepted by PDA, so can’t be regular. Similarly, L₂ can’t be accepted by DFA, so it is not regular. L₃ and L4 both require only finite number of zeroes. So, both are regular.
