16 bit ripple counter

Best answer is NO, but hard to be definitive without knowing how the clock/reset works on your 4b blocks.

Assuming positive edge clk and active high reset, then when you set rst low to enable the counter on the left, all

the other counters are held in reset because of the inverter in the reset line.

But if reset is high to enable all the counters on the right, then the one on the left is disabled.

So nothing will happen. Ever.

That being said, most ripple counters would just be a chain of, say, 4b counters, where q[3] of the prior block goes

to the clock input of the next higher block, and you would need falling edge triggered counters (or an inverter

in the path, assuming positive edge counters).

So, just google 'ripple counter' and you will see literally hundreds of examples.
