1.) "Ir" is an irregular verb, and the present first person form is "voy", and you got this right
2.) The sentence talks about multiple people here, meaning you'd have to use "les" and not "le" because it represents third person plural. You'd also use "gustan" because "deportes" is plural and not singular
3.) "Escuchó" is the preterite third person singular conjugation of "escuchar"
4.) "Tengo" is the present first person singular version of "tener". It also happens to be an irregular verb
