  We present MeerKAT HI observations of six jellyfish candidate galaxies
(JFCGs) in the galaxy cluster, A2626. Two of the six galaxies JW100 and JW103,
that were identified as JFCGs from B-band images, are confirmed as jellyfish
galaxies (JFGs). Both of the JFGs have low HI content, reside in the cluster
core, and move at very high velocities ($\sim$ 3$\sigma_{cl}$). The other
JFCGs, identified as non-jellyfish galaxies, are HI rich, with HI morphologies
revealing warps, asymmetries, and possible tidal interactions. Both the A2626
JFGs and three other confirmed JFGs from the GASP sample show that these
galaxies are HI stripped but not yet quenched. We detect HI, Halpha, and CO
tails of similar extent ($\sim$ 50 kpc) in JW100. Comparing the multi-phase
velocity channels, we do not detect any HI or CO emission in the northern
section of the tail where Halpha emission is present, possibly due to prolonged
interaction between the stripped gas and the ICM. We also observe an
anti-correlation between HI and CO, which hints at an efficient conversion of
HI to H2 in the southern part of the tail. We find that both RPS and HI-to-H2
conversion are significant depletion channels for atomic gas. HI-to-H2
conversion is more efficient in the disc than in the tail.
