Hello,
I recently came up into a configuration applied on a router that looks like this:
policy-map wan
class ether-wan-telephony
priority percent 15
class ether-wan-video
priority percent 10
class ether-wan-signaling
priority percent 5
class ether-apps
bandwidth percent 20
class ether-wan-bulk
bandwidth percent 40
class class-default
fair-queue
I thought you can have only 1 strict priority queue. Is this configuration valid? If you have more than 1 priority queue, which one takes precedence?

Yes it's valid.
All 3 classes are using the same LLQ but each with its own policer.
BTW, later IOSs (which your ISR 4k might have) support two LLQs; priority 1, often used for VoIP bearer, and priority 2, often used for video. (By the book, VoIP signally shouldn't be using LLQ.)
