Do you think that the girl is naive? Is the too innocent to understand death?

I think the girl understands death in her own way. In "We are Seven" Wordsworth looks at a young girl who had six siblings but now lives at home with only her mother, because two of her siblings have died and the others have moved away. The little girl seems not to understand death throughout the poem, but in the end the reader learns that she may have a clearer understanding than the speaker. In "Lines Composed a Few Miles Above Tintern Abbey" Wordsworth is comforted by the thought that he will live on after his death, because his sister Dorothy will remember him lovingly.
