What are the specific accusations? From this post, the only two I can see are that the pope is the false prophet and that some people seem to worship him.
Re: him being the false prophet, there are several things the Bible describes about the false prophet that seem incompatible with Pope Francis.
2 Thess. 2:3-4 says, “Let no one deceive you in any way; for that day will not come, unless the rebellion comes first, and the man of lawlessness is revealed, the son of perdition, who opposes and exalts himself against every so-called god or object of worship, so that he takes his seat in the temple of God, proclaiming himself to be God.”
In the first place, the pope has not proclaimed himself to be god. Far from it. He has repeatedly described himself as a sinner in need of prayer:
“Your Holiness, I want to ask why you ask so insistently that people pray for you?” “I have always asked this. … [If] the Lord does not help in this work of assisting the People of God to go forward, it can’t be done. I am truly conscious of my many limitations, with so many problems, and I a sinner – as you know! – and I have to ask for this.”

“When I speak of the Church I like to speak of the faithful, the baptized, the whole church, no? In that case, it’s better to speak of sinners. We are all sinners, no?”

Second, where is the rebellion that’s supposed to occur before he is revealed? The Great Apostasy should be more apparent. Yes, the world is growing more secular, but it was also very secular during the French Revolution. Secularism looked more like the Great Apostasy in the 1700s than it does in modern times. In that time, an actress portraying the goddess reason was enthroned on the great altar of Notre Dame Cathedral while the Catholics were being persecuted. If I had been alive, I might have thought the Great Apostasy was upon us. But it wasn’t. Now the pope comes to America and some people cry and wave their arms at him, and your friend thinks that’s proof he is the false prophet? Give me a break!
Third, when has the pope exalted himself against every object of worship (2 Thess. 2:4)? He seems to speak very gently and humbly about other religions, so much so that he is sometimes criticized as if he was indifferent as to what religion you are. (He isn’t indifferent about that, he has said very clearly that there is no salvation outside the Church, with all due qualifications where they are supposed to be.) But he certainly hasn’t done any self-exaltation to try to get other religions to worship himself instead. He’s just very different from the false-prophet.
2 Thess. 2:9 gives us another clue about the false prophet: “The coming of the lawless one by the activity of Satan will be with all power and with pretended signs and wonders.”
I don’t think very many people are impressed with any miracles Pope Francis has done. The closest thing, perhaps, was back when he leaned in close to St. Januarius’ blood, and it flowed. To me, that doesn’t qualify as “all power…with pretended signs and wonders.” So he isn’t the false prophet.
Re: the suspicion that people worship him, what is his evidence? Is it that people get very emotional about him? Sorry, but emotion is not worship unless you offer it as an act of worship. Worship is something you do with your will, it doesn’t happen by accident when you’re very emotional about a celebrated person visiting your town. I’ve gotten much more emotional about seeing my dog after a long absence than the people in Philadelphia are getting about the pope. But in both cases there is no worship because there is no intentiof worship.
