I have what I believe is a CXA tool post on my LeBlond lathe. In looking for additional tool holders, I see a number after the CXA such as #1, #2, etc. Is this number relevant? What does it mean?

See their catalog here: https://www.aloris.com/aloris_cat/31e970.pdf

The number following the size, in this case CXA, is the model number of the holder. As you can see in the catalog #1 is the turning and facing holder. Number 2 is the turning, facing and boring holder; it adds a vee groove to the bottom of the tool holding area to accommodate the round shank of a boring bar.

Yes, the numbers are just the style of holder. Turning; combo turning/boring with v-groove bottom; round boring bar holder; Morse Taper; Jacob's Chuck; multiple types of integral indexable insert; parting tool and plenty of others are options.
