Animation with 2 objects

I am very sorry that I write this in scripting category but there is no category such as “Animation Support”.

I am new to making animations but for now I am trying to do an animation where the player takes/sucks the blue liquid into the needle/syringe, hides the glass container and then injects it into his arm. I want to make 2 items being one tool, so the moment I equip it one item goes to left hand and the other to the right. I know how to animate the player but I have 2 major problems.

  1. I have no idea how to put the second object into the other hand.
    When I put both objects as one tool and there is one handle it is bugged, the container (which has the handle on it) goes to the right hand but the needle stays in place.

  2. I also want to animate the objects.
    I want the player to unscrew the container and also press the back button of needle (Don’t worry the objects are separated models, for example the needle is made out of 3 different parts), but when I go into the animation editor even though the objects are in the R15 Dummy used for animating, I cannot select them.
