These all look normal to me, but I am not a doctor or in any way qualified to examine poop. I am just going by the many diapers I have seen of my own kids and others over the years. Baby is generally happy and gaining normally yes? Not upset when nursing, generally? Any severe bouts of colic? Poop look alone is rarely a problem, but may be a clue to what is going on if there are other problems.
Please do not worry about foremilk-hindmilk. Despite the hype, It is simply a non-issue most of the time. Do not worry about how your expressed milk looks in a bottle. While it might make SOME babies uncomfortable, Babies can live and grow and thrive on nothing but foremilk if that should happen. If you continue to be concerned about foremilk/hindmilk, the easiest fix is to nurse more often if baby is willing.
With the bottle I would be more concerned (although not very, if we are talking the occasional bottle) about how much milk overall baby drank. Babies often overeat when bottle fed. If baby is bottle fed regularly, as in when mom is back at work and pumping for baby, then this tendency causes some issues. But not poop issues, more that baby does not nurse enough when with mom and mom cannot pump enough, and also, baby gets used to a fast flow with no effort and this can cause breast refusal. Paced bottle feeding positioning and technique for all bottles is thus a good idea.
Also if you have oversupply, pumping for extra bottles may exacerbate that situation. So in...
