リスク is a loanword used in business, health, and technical contexts much like 危険性, but it feels more modern and casual.
恐おそれN1
恐れ often means 'the possibility (of something bad happening)' as in 感染の恐れ, overlapping with 危険性 but carrying a more literary, cautionary tone.

安あん全ぜん性せいN2
安全性 (degree of safety) is the direct opposite of 危険性 (degree of danger).

危き機きN2
危機 means a 'crisis' (an acute, ongoing emergency), whereas 危険性 refers to the abstract potential for danger, not an actual unfolding event.

Compound of 危険 (danger) + 性 (nature, quality). The suffix 性 is commonly added to nouns to express an abstract property or characteristic.
