Can this product be used for swd with an arm processor?

Yes, the Black Magic Probe does support SWD as well as JTAG.

Can i use this with a saml21 and mplabx?

Should be able to, as the data sheet for the SAML 21 states "two-pin Serial Wire Debug (SWD) programming, testing, and debugging interface" which the Black Magic Probe does support (as it supports SWD and JTAG).

Can this be used to program nrf52832?

Yes, the nrf52832 is a SoC based on a Arm cortex-M4 CPU. The Jeff Probe runs a modified version of the black magic probe firmware, which is designed to debug/program most ARM CPUs
