It really varies; being in close proximity to the ocean, Boston's weather is very changeable. The city has certainly received large amounts of snow at certain times, such as the Blizzard of 1978 that paralyzed the city with nearly three feet of snow. But blizzards and extreme storms are not typical of Boston at all. In fact, most of the bigger storms tend to stay in the central and western part of the state, or go to the north of Boston.
Over the past several years, weather patterns went from one extreme to another-- in January 2011, the area received 38 inches of snow from a series of storms; but by late 2011, there was hardly any snow at all, much to the chagrin of ski-lodges; in fact, temperatures were unseasonably warm from September to December. So, while there have been months when Boston received 20-30" of snow, there were also months when hardly a dusting of snow was seen. If you are traveling to Boston, check the weather reports before you make the trip-- you may find plenty of snow, or you may find none at all.
11.5" was reported in Natick.
3 inches or maybe just 10 cm.
I do not have real-time information on current snow conditions. I recommend checking a weather website or local news source for the most up-to-date snowfall measurements in Cambridge, MA.

There were no reports from Cambridge, but reports from surrounding areas would indicate between about 14" - 16".

In January 2011, Worcester, MA received a total of 40.5 inches of snow. This was significantly above the average snowfall for the month, which is around 14 inches.

I didn't see an observation from Bridgewater, but judging by surrounding areas, they got about a foot or slightly more. You can look at dozens of reports for this storm in the area at the related link (which is time-sensitive, though there probably won't be another PNS for several days to outdate it).
