None.
That is an over 9-1/2-year old iPad model.
No Pencils work with any iPads that are over 7-11-years old.
None.
There are NO MORE third party smart, Bluettoth stylii that are made to use for an iPad that old, any longer, either.
Your iPad is too old.
Sorry.
With that old an iPad model, you are relegated to commonplace, found everywhere, simple capactive stylii that just transfer the ekectrical impulses from your fingers down through an aluminium tube to a large rubber tip that sends the electrical signsls to the iPad.
These types of stylii have NO pressure sensitvity NOR palm/hand rejection.
OR
capacitive stylii that use a clear disc tip ( the clear disc tipped ones are more accurate for writing or drawing ), but with the clear disc type of stylii, you should look for one that has a disc that is made from a clear, flexible material that will minimise any type of scratching should any type of grit or dirt gets on the tip.
(This little tidbit of warning applies to ALL stylus types as all can scratch your iPad’s screen if dirt and grit are allowed to drag on a stylus tip across the iPad's screen ).
OR
The so-called, fine tipped “Active”, battery powered ( most times rechargeable battery powered ) capacitive stylii, like many found on Amazon.
These fine tipped, “Active” stylii use a battery to send a tiny electrical current to the fine tip of these stylii that simulates an actual finger touch to the iPad's screen.
These types of stylii are not the greatest and many of these produce varying degrees of noticeable line jitter when drawing any type of angular lines.
Some of these “Active“ stylii do a better job at minimising this angular line jitter than others, but I have no idea which ones do minimise this better, so if searching for one of these on Amazon, you will need to read the reviews.
Lots of makers of active tipped, rechargeable battery powered stylii on Amazon.
Also, still need to make sure that these “Active” battery powered stylii are compatible with your IPad model.
Some of these, especially new to market ones, are NOT!
All of these these types of stylii work with all sketching/drawing/painting/writing apps, but without any palm rejection and/or screen pressure features.
You can use this stylus with other apps but will not be able to lay your palm on the screen, while you write or draw, unless you use special, non-body electrical conducting, lycra-based material drawing glove that works by isolating your hand/palm electrical impulses from the iPad's screen and allowing you to lay your hand/palm on the screen as you draw or write.
Something like these found on Amazon.

Some other glove makers, like these examples, found on Amazon, as well.
Sorry & Best of Luck to You
