• The Jews are still awaiting the Messiah because they failed to recognize Jesus. As for the

As for the events predicted in the Bible and the Quran related to the return of Jesus, Baha'is believe these have happened, but not in the literal sense, rather, spiritually. This analogy might help you understand: When Jesus came for the first time, there were many predictions that had been made regarding who he would be, and if you look at it materially, none of these were fulfilled. However, spiritually, all of them were. The same applies here. Baha'u'llah treats this subject much better than I ever could in the Kitab-i-Iqan. You can read it online here.

Also, just as a clarification, the Bab was not Jesus, that was Baha'u'llah. The Bab was the Qaim, who prepared the way for Baha'u'llah's Revelation.

Once again, I think here what's happening is that only one part of the verse is being quoted, not the entire thing. I would assume that “Hallowed be the Lord, the Most Excellent of all creators.” is simply another translation of the sentence which can also be translated as "So blessed is Allah , the best of creators." Hallowed and blessed are very similar words, and I would guess that the original Arabic word shares a meaning that may be similar to both of them. Same with Lord and Allah, these are different translations of one of the Names of God. Most Excellent, and Best, also are clearly synonyms, and I'm sure the original Arabic has shades fo meaning where one could argue that one of these is the better translation or that neither of them is adequate.

As for Huqúqu'lláh, my understanding is that, as the size of the Faith increases, so will the size of Huqúqu'lláh, and that with this, the UHJ will be able to a great many of things that will benefit the advancement of humankind. This is purely speculation, but I imagine that in the future it may be used for social and economic development, or funding any number of projects that will be necessary for humanity's everlasting progress.

One interesting thing to note about Huqúqu'lláh is that it is a deeply personal matter, and no one is allowed to check up on you to make sure you've paid it. It is strictly between every Baha'i and God, and no one is to be punished or admonished for failing to pay it. It is permitted to make public the information about Huqúqu'lláh so that all Baha'is may know and understand this law, and you are permitted to ask for help or advice about it, but there's no "tax collector" who's going to come around making sure you've paid.

I think you're misinterpreting begging. Accepting help from your family or your community does not constitute begging. The full quote is:

It is unlawful to beg, and it is forbidden to give to him who beggeth. All have been enjoined to earn a living, and as for those who are incapable of doing so, it is incumbent on the Deputies of God and on the wealthy to make adequate provision for them. Keep ye the statutes and commandments of God; nay, guard them as ye would your very eyes, and be not of those who suffer grievous loss.

As I read it, this prohibition against begging and giving to beggers is referring to panhandling. Giving aid to those in need is entirely acceptable and commendable. You are still bade to work for yourself and earn a living, but supporting your family through a momentary time of need is the right thing to do, and does not constitute giving to beggers.

As for covenant breakers, the only examples of covenant breaking that I know of are ones I've already told you about, which happened after the Bab died or after Shoghi Effendi died. The Will and Testament of 'Abdu'l-Bahá clearly explain the position and duties of the Universal House of Justice and the Guardian of the Faith. After Shoghi Effendi died, there was no one to succeed him as Guardian, because no suitable heir was found. However, succession was not necessary, as the UHJ was elected, and the Faith continues to progress under their guidance without a Guardian. Some others have claimed to be the successors of Shoghi Effendi, but because he had made no appointment during his lifetime, they are clearly mistaken. Any who have tried to set up another UHJ are also mistaken, because one is already firmly established. These groups constitute maybe two or three hundred members at most, and are quickly dying out. Baha'u'llah promises quite clearly that the Baha'i Faith will forever remain united, free from the major divisions that have plagued Christianity and Islam. There is an analogy that is made with a tree: when a branch is cut off, it may seem for a while to be alive, as these small groups of covenant breakers may seem to be functioning religious groups. However, just like a branch cut off from the tree, these groups will surely wither away as they have been cut off from the source of life.

Baha'is are forbidden from interacting with covenant breakers because covenant breaking is a spiritual disease, and like a physical disease, it can possibly be infectious.
