The plural form of a name depends on various factors, including the spelling and pronunciation of the name. In the case of the name “Chris,” there are a few different ways to make it plural depending on the context.

One way to make “Chris” plural is to simply add an “s” to the end, making it “Chrises.” This is the most straightforward and commonly used method. For example, “I went to dinner with two Chrises last night.”
Another way to pluralize “Chris” is by using an apostrophe followed by an “s.” This method is typically used when the name ends in an “s” or “z” sound, like “Chris,” to avoid having two “s” sounds in a row. For example, “I invited the two Chrises’ girlfriends to come with us.”
If you are referring to a group of people that includes both male and female individuals named Chris, you can use the plural form “Chrises” to refer to the group as a whole. For example, “There are three Chrises in our class.”
Finally, if you are referring to a group of people that includes multiple individuals with the name Chris, but you want to distinguish between them, you can use the full names instead of the plural form. For example, “Chris P. and Chris H. both applied for the job.”
In summary, the most common way to write “Chris” in plural form is by adding an “s” to the end, but the use of an apostrophe followed by an “s” can also be appropriate in some situations. When referring to a group of people that includes both male and female individuals named Chris, “Chrises” is an appropriate plural form. If you need to distinguish between multiple individuals with the name Chris, it is best to use their full names rather than the plural form.
