For some reason, Kiara always reminded me of a younger, cuter Britney Spears XD

That's a good point. Young Simba was based off Jonathan Taylor Thomas and Jeremy Irons was an inspiration for Scar. Moira Kelly said in an interview I've posted before they took pictures of her so I guess her physical features were used in Nala. Adult Simba is an adult version of young Simba. I don't know about the other actors.
