To form the plural of nouns in Spanish, there are a few general rules to follow. Let's apply those rules to the words you provided:

1. The noun "el lápiz" (the pencil) is masculine, and to make it plural, we drop the "-z" and add "-ces". So, the plural form of "el lápiz" is "los lápices" (the pencils).

2. The noun "la nariz" (the nose) is feminine, and to make it plural, we replace the "-z" with "-ces". Therefore, the plural form of "la nariz" is "las narices" (the noses).

3. The noun "el profesor" (the male teacher) is masculine, and to make it plural, we remove the "-or" and add "-es". Hence, the plural form of "el profesor" is "los profesores" (the male teachers).

4. The noun "el ratón" (the mouse) is masculine, and to make it plural, we take off the "-ón" and add "-ones". Thus, the plural form of "el ratón" is "los ratones" (the mice).

So, the plural forms of the given words are: "los lápices", "las narices", "los profesores", and "los ratones".
