The heirarchy is as Below
1> Shri Vishnu ---- The supreme
2> Shri Lakshmi -------- The next to supreme
3> Brahma /Vayu
4> Saraswati/Bharati
5> Shiva
6> Parvati
----- Hanuman /Bhima/Madhwacharya are avatars of Vayu & it is very wrong to call them avtar of Shiva
Ashwathama, & some the great gurus like durvasur, Shukacharya (who narrated Bhagvat purana to Parikshit) are all avtars of Shiva
