The names are triborane(9) and tetraborane(12).

The IUPAC rules for naming boron hydrides are:

Boron hydrides are called boranes, and the name of ${BH}_{3}$ $"BH"_3$ is borane.
The number of boron atoms is indicated by an appropriate numerical prefix.
The number of hydrogen atoms is indicated by an Arabic numeral in parentheses immediately following the name.

∴ The names are triborane(9) and tetraborane(12).
