I agree with dv1977, the black pull-tab on the left side of the chip is a great starting point. Heat will also help, so use an iOpener or something similar to heat the glue.
Again, you need a #000
Same here, just open the gap a little with the suction cup and then use the opening tool on both sides.
If you have a FlexCare 69xx handset, then Ralf is correct, no screwdriver needed, just push the metal part (brush holding part) hard to e.g. a wall.
The rest is the same.
