1. Repetition
And a pain still throbs in the old, old scars
2. Simile
And the river flows like a stream of glass;
3. Personification
Till its blood is red on the cruel bars;
4. Alliteration
When he beats his bars and he would be free;
5. Personification
When his wing is bruised and his bosom sore,--
6. Alliteration
When the wind stirs soft through the springing grass,
If you need more explanation for any of these questions, just ask and I'll explain it in more depth :)
Good luck!
