Can you use Create Demiplane, Greaters Portal feature to create a portal from the demiplane to a relative point in the material plane. Such as within 5 feet of a shield? So that you can have the entrance/exit move around in the material plane?
To clarify, I want the portal from the demiplane to the material plane to end up at near a specific object. So if the object moves, it will still end up were the object is. Then also use the said object as a portal to the plane. Basically I want a door to and from the demiplane attached to something such as a shield, so I can move it around.

Standard reply: ask your GM. The rules are vague enough that s/he should decide, based on how your game world work.
I, generally, would require something fairly big (at least door sized) or a specific item created when the plane is created, not something like "X shield". And never something that is worn.
A door mat that when unrolled and placed on the ground generate the portal? Ok
5' from this shield? No.
Standard general answer per the expectation of the game (from my view):
The frame of reference being used is the planet/plane where the portal exists. You must choose a point fixed on the planet/plane for it to always be.
More plainly, no you may not have a movable* entrance exit to your demiplane.
*Movable in this case meaning moving relative to local features, as a planet does orbit around a sun and rotates about its axis, therefore no location is truly "fixed" with respect to a universal reference.
But it is fixed with respect that it located specifically in the city of Absalom in such and such district in such and such house within the pantry. And no you can't move it.
Having a mobile portal is something that has happened. There's a map that acts as a portal to a demiplane, for example. I've had characters who tied a portal to a shrunken object that when opened is a stone archway and that's the portal. etc.
If it was the actual shield that was the portal then maybe. It's weird, but perhaps.
However, simply "near X Shield" is a bit too amorphous for my liking. Ask you GM, but i'd say it has to be the object and not simply near said object.

[Portal:
Your demiplane gains a permanent gate to one location on another plane, which can only be used for planar travel. This location must be very familiar to you. This gate is always open and usable from both sides, but you can secure it using normal means (such as by building a door around it).]A place only defined by being near a certain item is neither "a location" nor "very familiar to you" - so no, you may not.
As well, that statement "Your demiplane gains a permanent gate to one location on another plane" really sounds to me like they mean a fixed permanent location. Non-movable.
That there are items or adventures where things didn't follow this rule doesn't really make a difference. Wondrous items often don't follow the rules of the spells the emulate and adventures often do things "because plot".
I honestly think its too generous to players to allow them to carry around easy access to their demiplane. No, if you want to go there cast teleport (to get to the entrance) or plane shift to go there directly.
I'll point out (rushes off to check if they still exist within PF as my knowledge is per 3.5, comes back having double checked) that the Amulet of the Planes, Cubic Gate and Well of Many Worlds are or create portals to other dimensions and are quite mobile though none is created via Create Demiplane.
And ninja'd by Claxon more or less.
Power and balance wise the real issue for a GM is that the other 'end' of the magic items (vs a demiplane created with a Gate/portal) is pretty much random location not a fixed making it's portability less problematic. Still it basically comes down to the level of characters and overall power level of the campaign and how the GM envisions how the planes and demiplanes interact. It would be much less of an issue for me personally if the characters were near 20th and/or Epic/Mythic and accessing their personal demiplane was still also possible via other methods which could or might get used by other foes/rivals.
I'd have to agree that in general the RAW doesn't seem to support a portal fixed to readily man portable item, but I would agree to something more along the lines Diego mentioned up thread. A large carpet, wagon or ship might be mobile yet still doable as one end of the gate without serious issues.
Me and a friend are planning on running a drug cartel in a game another friend is going to run. We were thinking of putting a portal on my friends shield (he's a antipaladin). Then we jump through the portal in the shield when we need to access our demiplane, There would be chance enemies could jump through, but we would try to get some underlings to protect the portal.
Also the only problem with the random place in the demiplane is that my friend (unlike me by the time we get this plane) can't fly, so he would possibly end up endlessly falling due to the shape/nature of the demiplane. Or atleast keep falling till I carry him to safety.
If he can't fly he's going to be sucking in lots of level appropriate encounters.
One way to manage the random location of arriving in a demiplane via plane shift is to use dimensional lock if it's not very big. Just leave one small part not subject to it, you'll always arrive there and can focus your security. Or make a tiny safe demiplane that has it's own portal to your "real" demiplane. You travel to the pocket plane, then walk to the real one.
If it's affixed to the shield what happens when the shield goes through the portal, does it create an infinite mobius strip?
Mathius has a reasonable condition, that the portal could be affixed to some large mobile device structure.
The underlying issue is the portal needs to stay open on both ends, if its fixed to an object then that object itself can't go through its own portal, that's like putting bags of holding inside one another.
I had a similar idea where the the portal was the entrance to a large box. That was an animated object. That flew. And occasionally teleports.
I wanted a T.A.R.D.I.S.
I think a floating castle or a sea going vessel is acceptable now that you mention it.
Something large and difficult to hide.
Allowing people to place the portal is small objects that can be easily hidden on a person and easily moved about is too generous.

Yes. There is such a moving demiplane in Golarion canon. PM me for details - my players are listening... :P

The shield wouldn't go through itself... it would stay on the material plane...

And that is in keeping with the two other mobile demiplanes I know of. Mind you, the two I know of both have complicated access command words, like one long paragraph in an ancient tongue... I don't think you can "bump" into a demiplane entrance (or shield bash someone out of existence that way) :P
The LoF example is not pertinent, since the mobile object is artifact level.

Yes. There is such a moving demiplane in Golarion canon.Actually, two that I can think of right away... including one that is in the Legacy of Fire AP...
3.5 adventure (Just for the record).
An example of something similar is the Mirror of mental prowess. It do several other things, but look the price. And how little "portable" it is.

And a canny enemy that had divined what it do will throw it in a lake or ocean.
End result: a demiplane full of water.

I'm all for a moving portal, but I think the trick has to be that the object that makes the portal can't come into the demiplane (or optional it can but you either a) need another way out b) cause an implosion)
I'd be inclined to also restrict it to "you must open the portal from outside" so you have to leave your gate open. So you can't necessarily use your demiplane as a trojan horse unless you send it with instructions on how to open.
Just thematically I'm pro-the physically of the object defining the portal in some way, for example a tower shield that was literally a door in a frame that opened into your demiplane, or the above mentioned door mat you roll out. A magical pot of paint you have to draw on a surface, or something akin to a portal hole that you unfold and slap on a wall.
