This might be more apparent to speakers of languages other than English. There is a closer match in French, for example. It is not that planets are named after the days of the week. Both the days of the week and the planets are named after various deities that have been influential in human thought over the centuries.
In Roman times, the days of the week were named after the 7 visible planets (the Sun and the Moon were in those days considered planets). We have vestiges of this in English: Sunday, Monday, and Saturday are named after the Sun, the Moon, and Saturn. The names of the other four days got modified by replacing the names of four Roman gods with their Teutonic equivalents: Mars -> Tiw, Mercury -> Wotan, Jupiter -> Thor, and Venus -> Frigg/Freyja. It should be fairly obvious how those original names got worn down into the modern versions.
what planets did the romans use to name the days of the week
No, in the early days, and still today in all Rites of the Church, except the Latin Rite, the sacrament of confirmation is given immediately after baptism. Thus the name is given at baptism, and not repeated immediately afterward.
it varies
Hurricanes are given names to aid in communication and to differentiate them from one another. The World Meteorological Organization (WMO) maintains a list of names for tropical cyclones in different regions. The names on the list are chosen in alphabetical order, are gender-neutral, and alternate between masculine and feminine names. This helps to make identification and tracking of hurricanes easier and more efficient. Leslie is just one of the many names on the list.
