'Fraid the rules are against you here.
Ending Your Movement: You can't end your movement in the same square as another creature unless it is helpless.
No exception is made for standing on top of them. Pathfinder doesn't really deal with maneuvers like that, so the GM dealing is totally optional.

That creature would not end on the same square as the other creature, but in a square above the other creature making balance on top of it.
We're talking about a 3D environment.
Is there any official ruling or RAW statement that I can use to justify to my GM being able to stand on a hostile creature two size categories larger than me? I want to teleport above it and use my acrobatics skill to land and "balance" on it. Any third party or non official rules are no go for him. My character has a acrobatics bonus of 24.
There's no direct rule to cover what you're attempting, but you can perfectly achieve what you want just with CRB rules. Two ideas here:
1-. Use GRAPPLE rules to get hold of something and not directly fall. This actually works as intended (instead to one side, you end in a square OVER the creature). On posterior Maintain Grapple checks, if you succeed on the check you should be able to chose the MOVE bonus action, but since moving the target is absurd in that scenario, the MOVE action should allow your character to crawl instead while keeping hold.
2-. ACROBATICS check to just keep balance:
- SURFACE WIDTH: 0 (surface larger than 3 ft)
- THREATENED AREA: Target's CMD
- UNSTEADY: +2 to +10 depending on the creature's movement and actions.
- CONDITIONAL MODIFIERS: Creature Shape, Slippery, Sloped...
So, essentially, you might roll acrobatics vs the target's CMD plus some extras depending how much the target "shakes" to get rid of you and some modifiers depending on the exact creature. A (H) Elephant may not have extra modificers, but a (H) Ooze might perfectly count as a slippery (wet) surface (+2) and slightly sloped (+2) because of the round form. Also, for really big creatures, specific parts of the creature might have different DC values.
Of course, there are scenarios where either Grapple or Acrobatic would not be viable, but those must be considered in a case per case basis. For example, you might initially be allowed to make acrobatics checks to stay on top of a (G) dragon... but the moment that dragon takes flight and decides to start making Barrel Rolls to shake you off, either switch to grapple or get ready to kiss the ground.
Pathfinder doesn't do 3D well.
However we do have this rule:
A creature or object brought into being or transported to your location by a conjuration spell cannot appear inside another creature or object, nor can it appear floating in an empty space. It must arrive in an open location on a surface capable of supporting it.
Teleportation falls under conjuration rules.
This statement is enough for me as a GM to say no.
You absolutely can't teleport into the air and fall onto the creature, and while not written outright I find the statement enough to deny teleporting onto the creature.
For what its worth (I believe) there is a rogue archetype that gets a special ability to climb on an enemy that is larger than them.

That sentence actually cannot be applied to Teleportation if you check what it does apply to:
A creature or object brought into being or transported to your location by a conjuration spell...
1-. Brought into being: You already exist.
2-. Transported to your location: You're not bringing something to your location, you're actually porting somewhere else.
So, neither clause is valid for teleportaction. You might consider that other creatures ported with you are "transported to your location", but everyone is ported at the same time, you don't go there first and a split second later the others follow.
That sentence is actually meant for Effect aiming descriptor, that applies to most Conjuration (summoning) spells (along with many others). If you check the Effect descriptor, you'll find that the first sentence is extremely similar to the one you posted:
Effect: Some spells create or summon things rather than affecting things that are already present.
Some spells create ... things = A creature or object brought into being
Some spells ... summon things = A creature or object transported to your location
