I have a squash vine with numerous squash (10) on the vine at various stages and still growing. As it takes 110 to 120 days to mature, should I cut the new growth from the plant to help the existing ones to mature?

Cutting the vine may injure it so severely that the entire plant will die, and if it doesn't die it will become highly susceptible to disease. The younger squash will either not fully ripen or die off on their own if the vine ends its life by providing nourishment to bring the more mature fruit full cycle. Leave it be, and enjoy!
