Corrections in capital letters.
1. Don't use 'pareja'. It means 'girlfriend' or 'boyfriend'.
2. In Spanish, we don't 'play sports', we 'do sports' or we 'practice sports'. Not 'jugar deportes', but 'practicar deportes' or 'hacer deporte'.
3. 'Él' means 'he'. 'Ello' means 'that', 'that thing'.
4. 'Types of music that sounds good to him', could just be translated as 'types of music that he likes' > 'tipos de música que le agraden.
5. 'Muchos' is very similar to 'too many'. So it's kind of negative, that's why I used 'varios', which means 'many', 'several'.
6. Not 'amigo mejor' > 'mejor amigo'.
7. Not 'por el futuro'. Use 'para el futuro'. If you used 'por', it would mean 'because of'.
8. «He flew to France on a long trip.»
Travelling in any way is translated to 'viajar'. So, 'Él viajó a Francia'. Now, 'on a long trip'... Here, we can specify that he actually flew (by airplane), so instead of using 'viaje' (as a noun), I'm using 'vuelo' (flight, in Spanish 'flight' includes the whole journey). So we'd have: 'Él viajó a Francia en un vuelo largo'.
9. 'And (he) saw his family'. 'Vio' is a mono-syllable word, so it doesn't have a tilde over the 'o'. 'Parientes' which means 'relatives' is in PLURAL, so the possesive, will be also in PLURAL. 'Y vio a sus parientes'. However, if you want to stick with 'family', you can always say 'Y vio a su familia'. Remember, since 'family' (familia) is in SINGULAR, the possesive 'his' (su) will also be in SINGULAR.
Hope this helped.
