Yian kut-ku:
Weak spot: head or wings
Weakest element: ice/water
how to kill: attack it's legs until it trips over, it usually follows a certain attack pattern but i advise to attack the legs while it has been stunned by a sonic bomb/ small barrel bomb.
Khezu:
Weak spot: head
Weakest element: fire
Best weapon to use: king lion saber (don't worry it's an HR6 guild weapon)
Tactics: as the khezu can't see, it can only smell use dung bombs to your advantage. Always move out of the way behind the khezu when he is charging his electric attack this attack may prove fatal to your character.
Rathalos:
Weakest spot: head&wings
Weakest element: dragon
best weapon: smoulder dragonsword or eternal schisms (both HR6 weapons)
Tactics: when the Rathalos is in rage mode it is pretty unpredictable, i advise flash bombs when he is in rage or else you may die REAL fast. when he turns around slower then when he is about to charge at you he is going to shoot fire at you, run up to his head and slash him while he takes the recoil damage. The sign of him about to die is the limping he will go to area 5 to sleep, let him go to sleep and if you are using a greatsword slash him on the head to kill him if you are not using a greatsword the use a shock trap and spam him with tranq bombs.
