As far as I know, it is not possible to pass a range of parameters this way. However, assuming that your Incident.Status field is a string type, you can pass a concatenated string and change your query to test whether the status can be found in that string.
Javascript:
var params = {Status: "Active,In Progress,Escalated,On Hold,Resolved"};
Query:
FIND Incident WHERE INDEX_OF(Incident.Status, ?Status) >0
Alternatively, instead of INDEX_OF you could use MATCHES to apply regular expressions in your query.
Disclaimer: I haven't tested this approach, but think that it should work.
