Thank you for your question. This is not a jurisprudential issue such that it would be permitted or not, but such feelings may occur in an individual based on what they have understood of different prophets (as). The truth is that all of the prophets (as) are a reflection of the Prophet (saw) who was the most complete of them and so loving any of the prophets (as) is in truth loving the Prophet (saw) himself. The dichotomy arises in our minds due to the incomplete picture that history gives us. But if one is able to understand that there is no separation between the prophets (as) and that the Prophet Muhammad (saw) comprised all of what the other prophets had, while they did not comprise all of what he had, then they will come to the understanding that the Prophet (saw) is the most loved creature in all of existence.
May you always be successful.
