‘I made 5 different animations (called Hop1 to Hop5)’
How did you organize those animations ?
You can have as many animations as you want on an object but you have to assign a separated action to them and organize those actions in the NLA editor.
If your character is jumping up one time and doing a walk cycle the other time, you make an action for the jump, an action for the walk and in the NLA editor you can organize those actions so it jumps, walks, jumps, walks jumps, walks …
So, how did you organize those animations ?
To delete an animation from an object you select that object in the ‘Outliner’, expand the object’s directory by clicking the little ‘+’ sign in front of it. Right click on ‘Animation’ and select ‘Clear Animation Data’. In the action editor a ‘0’ will appear in front of this action and this action will be gone, next time you open Blender. Or unlink the action from the object in the action editor itself by clicking the ‘x’.
It would be a help if you could post the file so I can see what you are talking about and what you have done.
