Torque specs for front differential

My transmission had a ton of metal shavings and the fluid looked like mud to whomever has been following the previous posts, I took the transmission out and while doing so I unbolted wrong bolts for the front differential, I realized I did not need to take out the bolts to take the transmission out, I was wondering if anyone can provide the torque specs for the 5 bolts circled in red, I would also take specs for the 4 bolts in yellow for later purposes, thanks.

for want of what you asked.....

material and thread size gives you most of the info one needs to do up bots

only on modern stuff where they moved on from stiction impacted stuff - do we use new bolts, lube threads to spec, torque them to spec, and then turn x degrees to get a more accurate stretch on the bolt (to stop it falling off) and loading on the faces being clamped - its the way most head gaskets are done up and in most cases little different to old ways or on a con rod where it would be very sensible to do it correctly

yellow looks much like a wheel bolt - aka 60 lbs ft
red can't see but I'm guessing 30 lbs ft
