You Should talk with Tom about his views and outbursts. Obviously he is someone with strong beliefs and opinions but you should talk to him and ask him to relax them for the game because the game isn't targeting anyone or making anyone a evil person it is a character in a story. Also the bribing a DM or guilt tripping them in a sign of bad player behavior and should be its own conversation. As an addendum for his viewpoint behaviors remind him that this is a game and a fictional story where Tom doesn't have to be anyone close to himself. He can be a scholar of the arcane, a filthy barbarian from the wastes, a chivalrous knight or a dark and deadly assassin, a charismatic diplomat or even a evil Necromancer or a being who made a deal with a Devil for their power he is in this game who he wants to be and he doesn't have to be Tom the Wizard.
Max and Daniel you should talk to about their Murder-Hobo Antics, obviously it's fun to be a evil character or to be that strong edge-lord with few cares but actions have consequence and you need to both in-game hold him to that and out of game talk to him that such antics will result in him placing himself and the party as a whole in danger from backlash. Daniel if his issues are murder-hoboing and arguing with Tom, talk to him about holding back the arguments and same anti-murder-hobo antics I suggested above.
As for Mark and Alex, You should talk to Mark ask him if everything in game is going as he wishes and if he expresses concerns and complaints you should handle them as they come. Alex you should talk to him and ask if he is having trouble playing or adjusting, sometimes people who are really passive lack experience playing or the want or sometimes the ideas and perhaps you should talk with him and think of ways to invest him within his character and the world at large. Obviously if he just wants to watch, it is up to you to handle that but it seems most of them have conflicting attitudes and ideas about what is going on. I suggest you address every privately and converse with them about their issues and then address them as a party as a Session Zero. That can help iron out issue and create a playable game, however as DM you do have the authority to not DM with them or not DM so ultimately the only thing progressing and keeping the story alive.
To help I'll give you my hopefully not too rough but usefull example of me working with a group I DM'd with earlier last year only me and one other player had played D&D at all beforehand so we had a varied party of people. We had a group of six plus me. They had a few issues between passive players, to murder-hobos and then righteous values that often made in-game event seem very awkward. I approached the players privately to work with them on the issues which turned out well enough.The hardest part was working with them because some can take private conversations personally as an insult and in my experience the best way is to ask they how they feel and respond with how you feel. My party was a bit hardier on the interpersonal relationship aspect so saying that your actions/inaction in the game were not the greatest was easy and the hard part was figuring out why and how to fix it. which for some can be a simple character redesign for other it's working on understanding what they wanted out of the game
