No they are not pronouns but the don't much differ from our typical (she/her, he/him, & they/them) in Spanish you use (ella, el, elles/ellos). And you use ellos to speak abput multiple and elles for a non-binary person.
So if I made corrections it's be:
Nos gusta comer.
A el le gusta leer.
A ella le gusta ayudar.
