Well, Simba's Pride showed barely no other lions except the two lionesses on Simba's group during Kiara's cubhood so introducing more lions (including cubs) that obviously were in the pride is very easy.
There were no cubs intorduced for Simba&Nala's cubhood.
We don't see Mufasa and Scar's cubhood and the male lions from the former Guard were not present during events of TLK because Scar get rid of them.
And like Moka said, the movie features only characters that are necessary for the plot. Simon Wells (director of Balto, Prince of Egypt, American Tail) said "I think it was Hitchcock who said you can only remember five people you meet at a cocktail party, so there should only be five principle characters in a screenplay. This isn't a hard and fast rule, but it is generally true that you only have enough time in a movie to get to know a small number of characters with any depth." So introducting more characters that are unecessary for the main plot just for the sake of appearing is pointless and confusing to viewers.
