1) Angel Gabriel: Gabriel is the most well-known named angel to appear in Scripture. Each time He is mentioned, we see him act as a messenger to impart wisdom or a special announcement from God. In the book of Daniel, Gabriel appeared to the prophet Daniel in order to explain some visions God gave Daniel about the end times (Daniel 8:15–27; 9:20–27).

2) Angel Michael:who functions very differently from the angel Gabriel. Michael is an archangel, which means “chief angel”; this title indicates that Michael holds a high rank in heaven. Although it is not certain that Michael is the only archangel, the possibility exists, according to Jude 9, where Michael is referred to in definite terms as “the archangel Michael.” If other archangels exist, it is likely that Michael leads them.

3) Angel Lucifer(fallen angel): Lucifer rebelled against God and was thrown down from heaven along with the angels who followed him. Before his rebellion, Lucifer was a beautiful and powerful being; but he coveted equality with the Most High God and therefore became unholy and cursed (Isaiah 14:12–18; Luke 10:18). He is now known as Satan and is God’s chief enemy who seeks to deceive and destroy all of mankind (John 10:10).
4) Angel Apollyon(fallen angel): Apollyon/Abaddon is another fallen angel, mentioned in Revelation 9:11, who leads an end-times demonic army.

my questions are:
1) does it mean that heaven is another planet where normal human daily activities goes on where peoples are know by their names?
2) the much i know, 'Michael' and 'Gabriel' is a Hebrew name given to males, does it mean that the Hebrews and planet heaven shares the same culture and languages
3) i know there are a lot of other angels in heaven whom the bible did not mention and i also know that non of them bears an african names like Angel okeke, Angel Obasanjo, Angel Buhari, even Angel Atiku, then why?
4) i know according to the bible, till now no one have been to heaven because all will rise and be judge on the last day, then who are the 24 elders that bow down to worship God all the time, are they among the angels too?
