Salaam,
Thanks am for what you wrote above.
Has anyone stopped by and looked at what she wrote here? This is very important to understand.
Besides this, I don't know how always Rasool or Nabiyy is by default Muhammad? Is there no other Rasool or Nabiyy? And all aayaats are for today not for that period, we have to understand this.
May Allah increase us in knowledge and guide us to His only path

Peace be with you.
Okay, let's think about it in a different way.
Like you've said that all the ayats are also applicable for mankind today, so in this case, I think we are to love Prophet Muhammad (pbuh) more than the other prophets as per 9:24. But when it comes to showing respect to the messengers, then IN THIS CASE, we are not supposed to make any distinction. I say this because, I think it's not possible to love everyone exactly one hundred percent equally. For e.g. some people will love their parents more than their spouses, while some will love their spouses more than their parents. No matter what, it won't be possible to love them (spouses and parents) one hundred percent equally. And people may say that they love them all equally, but if you put them into a test, the result will tell you whom they love the most. The test can be like, if the spouse, and one of the parents are thrown into fire, and a person is said that he can only save one of them from the fire, and he'll have to let go off the other. So some people will choose their spouses over their parents and that will prove that those people love their spouses more, and vice versa.
Similarly, we all may say that we love all the Prophets equally, but no matter what, most of us will have in our hearts, a little bit more extra-affection for Prophet Muhammad (pbuh) compared to others. For e.g. if something comes on the internet against Prophet Muhammad (pbuh), like something very insulting about Prophet Muhammad (pbuh), then most of us will seriously become more angry and will feel more sad, compared to if something comes on the internet against Prophet Idris (pbuh) or Yahya (pbuh). We can't stop ourselves from feeling differently no matter how much we try.
And there is a verse in the Qur'an supporting this nature of human being:
And it will not be within your power to treat your wives with equal fairness, however much you may desire it; and so, do not allow yourselves to incline towards one to the exclusion of the other, leaving her in a state, as it were, of having and not having a husband. But if you put things to rights and are conscious of Him - behold, God is indeed much-forgiving, a dispenser of grace. (4:129)Here Allah is telling that no one can treat their wives equally no matter how much they try. And this also suggests that they can't love all of them one hundred percent equally.
So what I think is, despite some of us may be a bit more affectionate towards Prophet Muhammad (pbuh), and some may be towards Prophet Isa (pbuh) or Musa (pbuh), we all got to show the same amount of respect for every messenger, thus, not making any distinction between them.
Like we if say, "O Allah! Give Prophet Muhammad (pbuh) 100 mansions in paradise, and give Prophet Isa (pbuh) 50 mansions."....THEN THIS IS NOT ACCEPTABLE!...If we say 100 mansions for Prophet Muhammad (pbuh), then we also got to say 100 mansions for all the other messengers as well.
