3rd pic looks like iroko to me, though that florescent light is making it difficult to see any texture and real colour, but coming through with the crown cut.
A close pic with a shaded lamp would likely have a more accurate representation of colours,
and would likely show pore depth a bit clearer, iroko had deep pores.
However I don't see any other features which makes me think it's anything else.
Most similar common tropical timbers being yellower like idgibo, or yellow balau, paler
or redder like meranti, although some paler examples can look similar, same pore depth when looking closely at face grain, but being soft and mostly lighter is the giveaway.
The rest I've encountered when worked look different,
sapele smells strong when end grain worked, very red compared, much tighter pores
or sipo/utile, often has some fleck like beech.
