1. I have some bitcoin which I am planning to sell soon. I prefer real meetups and peer to peer deals. For that I need a good mobile wallet that I can send my coins to that I am about to sell. I have heard only good comments about Electrum but the Desktop version. The Mobile app lacks in the features department. What is a good Android phone wallet I can use for bitcoin? Trusted, non custodial, supports PIN or passwords to unlock, and no bugs.

Some people still use Mycelium wallet, others use Blue wallet, but I think Unstoppable.money wallet is worth checking out.
It is open source and it can work in your case if you need to use it as multicoin wallet.
I would not use any mobile wallets for storing bigger amount of bitcoin, but you can also use them in combination with hardware wallets for improved security.

2. My second question is not about bitcoin. For some reason people like tether where I live. It can be difficult to find a bitcoin trader. They prefer you convert your coins to tether and send them that instead of bitcoin. My guess is they fear volatility? I dont like it but I have to adapt. Can someone also suggest a good mobile and Android wallet that works with Tether and Tron? Same options like with the bitcoin one please.

You can use the same one I mentioned above, Unstoppable wallet.
One more option is called atomicdex.io and you can use it to make atomic swaps between various coins.

3. The only DEX I have read about is BISQ. I know nothing about it except that some consider it too difficult and overcomplex to use. Is there something else where I could convert my bitcoin to tether if I need tether? Only good DEXs please. I have had accounts being locked for months on popular exchanges and I dont want that again. Even if I want to trade live with people maybe it is not a bad idea to be able to withdraw USD or EUR from a DEX if possible to my own bank account. Do they work like that?

There are no other real DEX exchanges that works and have trading volume, especially not if real fiat currencies are involved.
For converting coins to EUR you can only use P2P trading, or use some centralized exchanges, maybe you can check best rates on bestchange.com, but dyor before using anything.
