I got real bored so here are my predictions/versions/HCs of some of the figured-out Numberblocks (with genders, talents and personalities included) in the future. That's it.
33 / Thirty-Three: Female; A very peppy and talkative girl who is able to spilt into three cheerleader squads, or two football teams and a cheerleader squad. She is the leader of the Semi-Prime Club and the best friend/girlfriend, of Thirty-Two.
34 / Thirty-Four: Female; A fancy/elegant yet positive and kind/generous fashion designer who creates nice clothes/accessories for her friends and is the older sister of Seventeen.
37 / Thirty-Seven: Male; A photographer with a habit of daydreaming.
38 / Thirty-Eight: Male; The local dentist and the older brother of Nineteen. He may sound and look scary, he's actually a caring and docile man with a beautiful voice.
39 / Thirty-Nine: Female; A smart yet timid Number Agent girl who spends most of her time reading books and writing books of her own. She is the sister of Twenty-Nine and the Opposite Luck Buddy of Twenty-One.
41 / Forty-One: Male; A one-off and full-time otaku, since he is an expert on discussing all-things anime (no matter how weird they are to some of his friends) with little to no problem!
44 / Forty-Four: Female; A feisty yet friendly tomboy referee and the non-identical twin sister of Thirty-Three (since the League of Elevens are siblings in my headcanon).
51 / Fifty-One: Female; A curious and naïve alien/Numberblock hybrid girl with an adorable voice to match. She, surprisingly, is a very good/close friend of Twenty-Six!
52 / Fifty-Two: Female; A Super-Rectangle and a full-time shepherdess who often has trouble herding her many sheep (as she's based on Little Bo Peep).
65 / Sixty-Five: Male; The calm and kind veterinarian of the Numberblocks; as well as owning an animal rescue center for animals who are old, abandoned, etc. in hopes of finding them new forever homes. He is the Opposite Luck Buddy of Thirty-Five.
66 / Sixty-Six: Female; The eleventh Step Squad, as well as the energetic and noisy sister of the League of Elevens. She is the zany (headcanon) girlfriend of Sixty-Four.
69 / Sixty-Nine: Female; A Merblock/Sirenblock girl who loves to sing beautifully to her friends.
77 / Seventy-Seven: Female; A hair and beauty expert who loves fairy-tales and cute, colourful things, as well as being a bit ditzy.
79 / Seventy-Nine: Female; A peppy and sweet baker who loves to make cakes, fresh bread, etc. for her friends! She is the (headcanon) sweetheart of Eighty-One.
88 / Eighty-Eight: Female; A female Octoblock who loves to study about constellations and magic. Got the idea from StarRion20 .
91 / Ninety-One: Female; the thirteenth Step Squad and can be either lucky or unlucky, depending on how she feels. She is the Opposite Luck Buddy of Forty-Nine.
130 / One Hundred-and-Thirty: Male; The Tens version of Thirteen and the Opposite Luck Buddy of Seventy. While not being as lucky as Seventy, One Hundred-and-Thirty gives his friends hugs that make anyone happy!
Since I'm doing Mugen Gemblock forms for the canon Numberblocks since late February, I've done this chart/list to keep track of the Gemblocks forms I did and the ones I'll do later on (as well as adding them when I do them, of course)! I'm so happy to do this as a big project made BY a fan, FOR the fans! 
Mind you, the ones I'm currently doing are for the canon/figured out Numberblocks. Just to let you know.
List of the Gemblock forms (so far) done by me:
Forty
Forty-Five
Forty-Nine
Fifty
Fifty-Five
Sixty
Sixty-Four
Seventy
Eighty (aka Super Octoblock)
Eighty-One
Ninety
One-Hundred
Two-Hundred
Brothers and sisters, let me set the scene
for a nightmarish creature so foul & obscene
that penning this poem makes me want to scream,
but the timing is perfect - for it's Halloween.
So, if we must, let's just start at the top
of his oversized skull with his unruly mop
of so-called hair the no-color of dust
on a fissured scalp peeling & leaking out pus.
His locks wind 'round horns, they're teeming with germs,
and look more like the husks of a million dead worms.
You've heard of bats in the belfry?
Well, it's not just a phrase;
small ones nest in his curls to hide from the sun's rays.
One more word on his noggin, for this must be said:
it's ten times the girth of a normal-sized head.
And if I haven't yet made the case for distaste,
let's move to the horror this thing calls a face.
Skin's the color of pumpkins dying a slow death
or a failing sun breathing its very last breath.
Brows like hairy slugs perched on orangey dough
crown flat yellow eyes peeking out just below.
Those beady orbs nestled in pouches and folds
of flesh home to all sorts of fungus and molds.
I suppose that's a nose next up on the list,
but it's rotting & roaches peer out through the slits.
Lips: scaly twin creatures all coated in muck,
like two lizards who crawled in some mud and got stuck.
Yes, his mouth is a marvel of nature's mistakes.
He has not one tongue - he has twelve made of snakes.
Oh, that slithering nest-hole just can't resist
striking at themselves as they writhe and they hiss.
And it's best if we speak even less of his teeth,
but they're green as the serpents who sleep underneath.
Now, we've seen enough here, so we shall begin
to speak of the mess under his bulbous chin.
And what appears next is not what you'd expect,
but two giant flaps like his neck... ate his neck.
His dermis is saggy, his guts are all stored
in a carcass that's shaped like some mutated gourd.
Yet he wears tailored suits, expensive and fine
that cling to limbs clunky and elephantine.
At the end of each arm is a claw like a crab.
The horrid appendages pinch and they grab.
He keeps them well sharpened and shined to a sheen,
but they are so small they can hardly be seen.
This would be almost a humorous twist,
if only this beast didn't really exist.
His mountainous legs suffer from the same flaws,
capped off in feet as tiny as his claws.
His whole frame reeks of sulfur.
He's covered in grime.
He leaves a lingering trail of malodorous slime.
This journey, I know's been an unpleasant one.
Dear reader, hang in there. We are almost done.
He lives in the depths of an ill-smelling bog,
shrouded at all times in a venomous fog.
Lit by giant mushrooms
with an unearthly glow,
a sick, swampy kingdom where twisted things grow.
A pestilent monarch, he squats on his throne;
sips gallons of blood from a goblet of bone.
His subjects are legion, they flock to his side;
all manner of ghouls that the heart can't abide.
There's a pale hateful zombie,
who's bedecked in flies,
and humanoid shape that has fanged mouths for eyes.
There's a three-headed harpy who screams at the sun
and a man-eating frog that weighs nearly a ton.
One could spend forever
trying to describe
the monsters that make up his hideous tribe.
But our time draws to a close,
my stalwart friends.
Lock your doors, say your prayers -
for this is THE END.
