To be fair, I can point out to a few concepts that I can see, how those prophecies share with what Baha'i theology teaches.
For example, Buddha said: .'I am not the first Buddha Who came upon this earth, nor shall I be the last. In due time another Buddha will arise in the world"
In the above prophecy I can see the concept of 'Return' of Manifestations of God. So, Buddha says, He is not the first Buddha, nor the last...meaning that a Buddha always returns to the world to teach the Truth, and since all the spiritual Reality of these Manifestations is the same, it can be said, they are all "Buddha". So, for example, Jesus was a Buddha, Moses another, and Baha'u'llah another Buddha. Similar concepts exist in Christian Bible, and Islam. For example, Muhammad said 'I am all the Prophets". Jesus Promised He shall return. Elijah a Jewish Prophet is said, He would return, and Jesus said John the Baptist is the return of Elijah.
Likewise Krishna, a Manifestation of God said He comes again and again to teach the Truth. Likewise 'Ali', the first Imam of Islam, said 'I was with Noah, and with Jesus', meaning, I am the return of the previous Holy Ones.
Another sign in those, is that, according to Prophecies you posted, whenever the Truth is faded and disappeared, the Promised One comes to teach the truth again. This is a fundamental teaching of Baha'i Faith, and can be seen in the sayings of Krishna, Zoroaster, Muhammad...etc. All of these in a way Promised of yet another Manifestation in future who would teach same Truth, so for example Muhammad Prophesied of another Manifestation by the Name of 'Mahdi', who would come and teach the Religion again, when the Religion is corrupted, or when that truth is disappeared.
So, while those Prophecies may not point to some physical signs, but the concepts are Baha'i or Christian, which is note worthy, considering Buddhism is not even an Abrahamic Religion, and yet shares similar concepts.
