I have been looking for a basic RPN calculator that the display shown 4 lines of the stacks X, Y, Z and T
Functions including percent and square root with 4 Store Register Arithmetic.
Nobody make this kind of basic RPN calculator on the market.

The SwissMicros DM42 offers all that, plus much more. Based on Free42 from Thomas Okken, which in turn was based on the HP-42S, it is the ultimate RPN calculator. You mentioned a 'basic'' calculator - this is obviously much more than basic, but it is as easy to use as a Voyager and offers display of XYZT and LastX, in various font sizes and styles, allowing it to easily be adjusted for your preferred appearance.

Highly recommended!

As much as I love the DM42 (I own two - a Beta and a Shipping unit), I got the impression that the OP was looking for a four-banger but using RPN and including none of the other functions. The DM42 would be too complicated for his (or her) needs.
