Icon No. 2 - help to understand who the saints are depicted

[origami]

Good day!
there's such an icon. Do I understand it correctly (after reading the forum) that this is "Krasotka"? Approximately what time? "Only spiritual value" or cultural material.
Poorly preserved, restoration, probably the most expensive of the icon?

And most importantly - who is depicted on it, do you think? Above figures have inscriptions in red, but can not read, they are too corrupt the Woman is Paraskeva, maybe?

Thanks in advance for your help!
