Should any moves of my Infernape knows be changed it knows 1 blast burn 2 close combat 3 flare blitz 4 flamethrower

You should teach it based on your Infernape's stats. Most Infernape have good speed, special attack, and attack. More of them have good special attack. A good set would be moves that cover its weaknesses too. Infernape is very frail at its defenses. A move should be able to take down a strong Pokemon with one shot. For example, Infernape can knock out a Staraptor or Pidgeotto with Stone Edge. So I recommend: Flare Blitz/Burn Blast, Focus Blast/Close Combat, Stone Edge/Rock slide, and Earthquake/Thunderpunch. I prefer Earthquake due to its abilty to hurt Dewgong or Entei which might use Dive or Dig to take down Infernape. GOod luck!
