The radiators in the hot rooms need smaller vents so they take longer to heat up, and/or the radiators in the cooler rooms need larger vents so they heat up more quickly. Some steam vents have a dial you can adjust like this, others have a replaceable orifice like this one - I got two of them last year and in spite of their low price they work perfectly. If a vent is not adjustable you can replace it with another vent.
Also, the headers in the upper floors may have undersized vents. My house has two headers. One is a short headers supplying 5 rooms, the other is a long header supplying 2 rooms. The rooms supplied by the long header took a long time to heat up, so I replaced the slower header's vent with one of these and it heats up much faster now. It cost me $75 if I remember correctly, but it was well worth it. It has much more venting capacity than anything with a similar price.
One last thing: see the diagram here: https://www.gorton-valves.com/products In general you want small capacity vents for radiators near the boiler/with short pipe runs and large capacity vents further away/with longer pipe runs so the system vents all the radiators at about the same time. It's part experience and part trial and error.
Yep, that vent is bad. I'd recommend a replacement ASAP, probably would go with a Big Mouth from Barnes and Jones inc for the replacement. https://www.amazon.com/Barnes-Jones-Big-Mouth-Vent/dp/B01F26P13C
