    Unfortunately, your photos did not come through. Typically, removing growth before flowering is a no-go for these shrubs. Any time that you do so, it will halt flowering for that year.

    The easy answer is to scratch the bark off one of the branches. If it is a bright
    green color, it is alive and may need water. If brown, it is likely dead.

    No. I would not do any work until the dormant season. Autumn to winter is the most appropriate time for this, but they can handle being moved right before breaking dormancy in spring, as well.

    Frost heave causes this problem often. Replant the rhododendron as if you were transplanting it. The formation of ice under the rhododendron makes conditions favorable so try controlling the amount of moisture when winter approaches. Insulate with 3-4” of mulch and monitor plants during winter.

    Both now and fall will be highly inappropriate. I would wait until winter when it is not actively growing. This isn't necessary and should only be done in the case of disease and heavy overgrowth, however.

    Unfortunately, your photos did not come through. I am unable to see the issue at hand.

    If this branch with different flowers originates from the ground, then it was likely a seed that had germinated and grew. You can remove this from the ground, getting as many roots out as you can, and the other should continue.

    If this is a branch that originates from higher up on the plant, then it could be a mutated sport. Sometimes, destroying the spot where the differently colored flowers originate will stop the coloration from returning.

    In the meantime, this collection of articles will help:
