The plural of يقظان is يِقَاظٌ, and the plural of يقظى is يَقَاظَى.

The first and second also mean: a man vigilant, wary, cautious, or in a state of preparation, having his attention roused; and intelligent. Or: a man having his attention much roused, very vigilant, and possessing knowledge and intelligence.
[In the TA, each of these two adjectives is said to be after the manner of the relative noun; but they are both ism fāʿil from يَقِظَ, as synonymous with تيقّظ.]
