* Sometimes "y" is a vowel: It acts like a vowel in words like "my," "fly," and "cry."
* Sometimes "y" is a consonant: It acts like a consonant in words like "yellow," "yes," and "you."
In the word "funny," "y" acts as a consonant because it's followed by another consonant ("n").
So, the answer is no, the "y" in "funny" is not a vowel.
