Eeschema: selectable anchor position for labels/pin text

Now it possible only for horizontal labels

I can't see your problem. I can rotate any label in 4 direction (at least in Windows version eeschema).
Check attached video. (rotating label with R key)

Do you want letters (or maybe non-latin characters) vertically one-above-another, but individual characters standing horizontally?

I want that label will be in the right side at relative of wire in vertical orientation (now it is possible only in the left side)

Now I see. Your attached lables.png is deceptive: x and y should be rotated.

You want something like my attached jpg.
If label orientation is "up", the anchor of label (small black rectangle) is on the bottom right, so if you place the anchor on the wire, label will be to the left of the wire.

You may need to re-position the anchor from bottom left (at normal left-to-right label position) to top left.
Label properties window needs an additional radiobutton group like "Anchor position". The only problem, that in normal view the label's anchor is not displayed, so it would be hard to realise which label belongs to a particular wire if there are multiple parallel wires.

Yes, this is what I want.
P-CAD support that feature.
P.S. I want to replace P-CAD to KiCad in my work place.

Example implementation from Adobe Illustrator.
