Will I be able to send the clock bpm from a pocket operator through the sq1 and out the midi 3.5 to a 5-pin and into a looper or a hardware synth?

Yes, you can. You will need an adapter or split cable to separate stereo (TRS) output from the Pocket Operator to two mono (TS) cables. On the Pocket Operator, hold the 'funct' button and press the 'bpm' to select SY1. The left becomes the clock and the right becomes mono audio output. The left clock pulse cable goes to your SQ-1. Adjust step resolution by holding the SQ-1's PLAY/STOP button while powering on (https://www.korg.com/us/products/dj/sq_1/faq_tips.php). It would probably be a good idea to not connect a USB cord even though analog clock pulses are supposed to take precedence. Start/stop signals are not recognized. So, press the PLAY/STOP button on the SQ-1 first, then press 'play' on the Pocket Operator. If your SQ-1's step knobs are all blinking really fast, then increase the volume of the Pocket Operator. One button above default did it for me. With the SQ-1 playing the output tempo that goes through the MIDI out is the same as the sync tempo. I did this with the SQ-1's MIDI out to an Arturia BeatStep Pro and the tempo was steady at 80 bpm, but fluctuated by +-2 at 140 bpm. The tempo change was rapid enough to sound like a some swing time or groove. Older kit seemed more steady.

I just bought a used korg triton le, if i hook my triton to this can i record samples on my daw in my computer?

Hi, no not at all. No. This is a compact step sequencer with 2 x 8 steps. It's meant to connect various synths together to be controlled by the SQ-1. It really has nothing at all to do with recording anything. Please let us know if you have any other questions. Thank you, The Midi Store Team

New to this. Is it possible to daisychain two of these together to go from being a 2x8 to a 4x16 sequencer?

Yes, but you would only have 2x16 or a 4x8 sequencer. If you want 4x16 you'll need to link 4 together

Does this device come with usb adapter?

It comes with batteries but no usb cable. If you use usb then you don’t need batteries. So if you want to connect it via usb you need to supply the cable.
