Daniel 2:17

2:17 Then Daniel went to his home and informed his friends Hananiah, Mishael, and Azariah of the matter.

Daniel 1:7

1:7 But the overseer of the court officials renamed them. He gave ¹  Daniel the name Belteshazzar, Hananiah he named Shadrach, Mishael he named Meshach, and Azariah he named Abednego. ² 

[1:7]  ¹ tc The LXX and Vulgate lack the verb here.

[1:7]  ² sn The meanings of the Babylonian names are more conjectural than is the case with the Hebrew names. The probable etymologies are as follows: Belteshazzar means “protect his life,” although the MT vocalization may suggest “Belti, protect the king” (cf. Dan 4:8); Shadrach perhaps means “command of Aku”; Meshach is of uncertain meaning; Abednego means “servant of Nego.” Assigning Babylonian names to the Hebrew youths may have been an attempt to erase from their memory their Israelite heritage.
