It would be this way (notice the orderby and meta_key properties):
$facultys = get_posts(array(
'post_type’ => 'faculty’,
'order’ => 'ASC’,
'orderby' => 'meta_value',
'meta_key' => 'role'
'meta_query’ => array(
array(
'key’ => 'location’,
'value’ => ”,
'compare’ => 'LIKE’,
),
array(
'key’=> 'role’,
'value’ => ”,
'compare’ => 'LIKE’,
)
)
));
But, it seems that you want to order the post in a specific custom order which is not alphabetical or numerical (I’m saying that because ‘Assistant Teacher’ is after ‘Teacher’, while the rest are in a alpha order). In that case, you should create four get_posts queries (it could be the same in a loop, only changing the role value), each query with the specific role.
