"Ele continua aqui."

Translation: He is still here.

A little confusing no?

[rmacheshire]

A literal translation does not work well here. It is best to translate the sentence as a whole into something that sounds OK in English. However it is sometimes hard to understand Portuguese idioms, and Duolingo generally prefers rather literal translations, so you can´t always get it right.

Can it also have the meaning of 'he continues here' as in someone giving directions?

[LaisReis1]

It could mean that, yes, but if that was the case, I'd imagine myself pointing at a map, at a certain street or whatever and saying "Então, ele continua por aqui..." .

Now, if there is no map, I would opt for... "Ele segue". The verb seguir has this more of "location" sense.

"Ele segue até o fim da rua", "Ela deverá seguir/continuar até o fim da avenida"

[JoshuaGambrell]

Is it any more unnatural in Portuguese to say "Ele ainda está aqui," or are they roughly interchangeable?

[Paulenrique]

Yes, you can also this translation also.
