Hello!

Please see my answers below.

1. No, those are the available clock sources.

2. I tested 2 Mbps with my board and it worked correctly, I used lpuart_interrupt example and TeraTerm. Please check it below.

You should also take into consideration LPC-Link and windows FTDI driver limitations. I recommend you to measure UART signals directly using oscilloscope or logic analyze.

I installed Tera Term Software, but maximum baudrate for serial port was 921600, How did you get 2000000 baudarte

You can manually write it even though there is no 2 Mbps option.
