Can I have more than one iQ open?

No, iQ’s are designed to be a live quiz used in class.

You will need to close the first iQ before you can open another. Students are only able to participate in one iQ at a time. 

You should not try to assign an iQ before your lesson. This can interfere with another teacher's lesson. If you assign an iQ to a class, the students in that class can not participate in an iQ assigned by another teacher.
