How to filter TCP SYN that has their bits set to 1?
I'm trying to understand how to use filters, how would I filter to find TCP SYN with their bits set to 1?

You didn't specifically say display filters but will assume you're working with an existing capture.
Either of these will show frames with the SYN bit set:
tcp.flags.syn==1
or
tcp.flags & 0x02
If you want to exclude SYN/ACK frames and only show SYN use this:
tcp.flags.syn==1 && tcp.flags.ack==0
