Books, bird, blind man.
The stacks of books:
AbdAllah ibn 'Abbas (ra) used to collect loads of books, so it might fit, it might be Abu Hurayrah (ra) but since his nickname is father of the cat, it appears that some of us assumed that the author intended one pic for each sahabah, Allah knows best.
The bird, Abu 'Umair's bird died and the Prophet pbuh is reported i think in Sahih Muslim to have wanted to lighten him up with the rhyming: O Abu umair what did nughair?
The blind man's walking stick appears easier since the most famous blind man in Islamic history is Abdullah ibn umm makhtum who is also alluded to in surah 80 'Abasa.
I think bro ibn Adam and Farhan did better with the bow and arrow since even the Prophet pbuh is reported to have picked up arrows for sa'd to shoot, i chose suhaib because i first remembered his lone standoff with the pagans during his hijrah, and salamah (ana ibn al akwa) because he also had a lone standoff when they tried to approach him and failed.
God knows when brother ridwan is going to publish what he intended, the others appear pretty straight forward.
