Peace be on you.
There are more aspects too about dajjal:
Quotes:
The word Dajjal has two connotations: First, it signifies a group which supports falsehood and works with cunning and deceit. Secondly, it is the name of the Satan who is the father of all falsehood and corruption.

Dajjal is not the name of one man. According to the Arabic lexicon, Dajjal signifies a group of people who present themselves as trustworthy and pious, but are neither trustworthy nor pious. Rather, everything they say is full of dishonesty and deceit. This characteristic is to be found in the class of Christians known as the clergy. Another group is that of the philosophers and thinkers who are busy trying to assume control of machines, industries and the Divine scheme of things. They are the Dajjal because they deceive God’s creatures by their actions and tall claims as if they are partners in God’s dominion. The clergy are arrogating to themselves the status of Prophethood because they ignore the true heavenly Gospel and spread a perverted and corrupted version as the supposed translation of the Gospel.

Remember, the sum total of the evils which the Holy Prophet (peace and blessings of Allah be upon him) prophesied would spread in the latter days, is Dajjaliyyat, of which the Holy Prophet (peace and blessings of Allah be upon him) has said there are hundreds of branches. Hence, those Maulavis [DawudTalut says:
those clergies who call themselves Muslims but spread terrorism and discord worldwide, many Ahadith explained their negative role in latter days] are also branches of the tree of Dajjaliyat who blindly follow the beaten path and have abandoned the Holy Qur’an, so that though they recite it, it doesn’t get past their tongues. Today Dajjaliyat is spreading its web like a spider. The disbeliever with his disbelief, the hypocrite with hypocrisy, the alcoholic with his drinking, and the Maulavi with his preaching without practice and with his black heart, are all weaving the net of Dajjaliyat. Nothing can break up this web but the heavenly weapon, and no one can wield this weapon but ‘Isa who should descend from that very heaven. So ‘Isa has descended and the promise of God was bound to be fulfilled.

The word ‘Messiah’ refers to the truthful one whose Masah (i.e. touch) as been blessed by God, and whose breath, word and speech have been given the power to give life. This word particularly applies to the Prophet who does not wage war and reforms mankind through his spiritual power alone. As against this, the word ‘Messiah’ also applies to the Promised Dajjal whose evil power and influence produce calamities, atheism and faithlessness. Even without employing coercive means to destroy the truth, he can make righteousness and love for God grow cold merely by concentration, speech, writing, association and by the influence of his satanic spirit. On the other hand, misconduct, drunkenness, lying, promiscuity, materialism, fraud, tyranny, oppression, famine and epidemics become the order of the day. These are the meanings which emerge from a collective study of standard Arabic lexicons like Lisan-ul-‘Arab;

"Mahdi leading the prayer with Jesus behind him?"
A Hadiths called Jesus as Mahdi
"It is just possible that he who lives of you might meet Jesus the son of Mary who is the Mahdi and a just judge. He will break the cross and kill the swine..."
(Masnad Ahmad Bin Hanbal, Vol. 2, p. 411)
"There is no Mahdi but Isa."
(Ibn Maja, Bab Shiddatuz Zaman)
B
Mahdi means 'guided by God' .
There are other Mahdis too, mentioned in Quran:
[21:74] And We made them leaders who guided
people by Our command, and We sent revelation to them
enjoining the doing of good works, and the observing of Prayer, and the giving of alms. And they were worshippers of Us
alone.
The initial words are ' wa [and] jaalnahum [We made them] aaimmatan [imams] yahdoona [who guided (people)] be-amrena [by Our command]' ---------
Result: We [i.e. Allah] made them [i.e. Prophets are mentioned in earlier verses] Imams who guided people......Obviously Prophets were guided by God then they guided people.
Thus , IN LIGHT OF A & B
your question "Mahdi leading the prayer with Jesus behind him" means
=This second Jesus is guided by God too, and is a Prophet too (obviously sub serviant to Holy Prophet pbuh)
=Being devotee servant of Holy Prophet Muhammad (pbuh) , he is leading in offering Salaat / Prayer i.e. he is establishing The True Version of Islam in latter days.
It has been written in my previous post #29
Who is the real Imam Mahdi? Is he still to come?
that Holy Prophet Muhammad (pbuh) mentioned two different men with different dispositions with one name Jesus. First was seen with passed-away Prophets....... The latter one was mentioned in relation with Kaaba and dajjal i.e. he would establish Islam and contend dajjal spiritually.
Such commonality in names exists in religios metaphors, e.g, John the Baptist was called Elijah.

@ injuntrouble said "But I don't get the Dajjal stuff - has Mirza Ahmad already killed the Dajjal as predicted while he was on earth? Or is it the standard explanation used by all religions - the prophecy is just metaphorical!"
Answer: The works of second Jesus are told by Holy Prophet "killing dajjal, breaking cross, kill swine,...more" [Bukhari, Masnad Ahmad]
So one can easily understand what these attributes really means. Obviously these are processes to be done by prayers, spiritual attentions, and establishing morals, conveying message but surely not with swords, guns, missiles, aeroplances etc..... That is why, Promised Messiah, Covenated Mahdi 's Jamam'at under Khilafat is struggling with all-spiritual-moral means to establish true Islam by the grace of Allah the Exalted and treasures of prays done by Holy Prophet (peace and blessings of Allah be on him) and all pious ones.

Lastly, door to ask by supplication, Who sends, is always open by His Grace.
