Ok that is 6, although Restrained or Exhaustion-5 will affect how you can cast Plane Shift, so you would not be "completely unaffected" WRT that spell.
Which would be 7
Which is all the spells you listed, except Blink, Fireball, Plane Shift and Forcecage.
And this would be 8, and I will point that while you can cast Fireball and Forcecage while blinded, you would not be able to see where you are casting it on or who is in that area and as such it is incorrect to say you would be "completely unaffected".
So you are up to 8 conditions and down to 1 spell you are "completely unaffected" casting - Blink
Charmed will prevent you from targeting the charming creature with a harmful spell, which includes Maze, Plane Shift, Hold Person and Dominate Monster, but we already eliminated those anyway and this would be 9 conditions.
So to correct your statement above:
Someone casting Blink is "completely unaffected by the caster having 10 9 different status effects"
That quite a bit different than your original claim.
