Is this schedule good for muscle gain? How much food?

[A_N_91]

This is what my weekly workout schedule is like...

Monday
AM-HIIT
PM-Workout
PM-Boxing

Tuesday
AM-HIIT
PM-Boxing

Wednesday
AM-HIIT
PM-Workout
PM-Boxing

Thursday
AM-HIIT
PM-Boxing

Friday
AM-HIIT
PM-Workout
PM-Boxing

The HIIT is 40 minutes of intervals and sometimes I switch it up to a steady state for 40 minutes. HIIT is only done for conditioning purposes. The workouts is a 5x5 program. The boxing is 5x a week for 2 hours and it's mostly just work on skill and technique, not alot of calorie burning.

Is this good? My main goal is to gain weight. But another question, how much food should I be eating (calories, P/C/F)??
