Morphology
on + first-name + terms
The meaning is directly and transparently compositional: 'terms' refers to the way people relate, 'first-name' specifies that the mode of address uses given names, and the pattern 'on ... terms' (as in 'on good terms') indicates the type of relationship. This construction follows a regular English combination and has clear parallels in other languages, so a B1 learner who knows the constituents should be able to infer the meaning.
Etymology
On first-name terms comes from the simple image of people dropping formal titles and calling each other by their first-name instead of 'Mr' or 'Ms'. So, being on first-name terms means you have a friendly, 'informal' relationship.
