There are masculine names with no COMMON feminine forms, but there is no such thing as a masculine name which could NOT have a feminine form. They can always be created by adding a femininzing suffix.
Many of the names on your list have well-known feminine forms.
Harriet and
Henrietta have been feminine forms of
Harry and
Henry used commonly in English speaking countries ever since
King Charles I of England was married to
Queen Henrietta Maria.
Marcia is a feminine of
Marcus and can also be used as a feminine of
Mark, and it's not hard to find examples of women named Markelle or Markette.

Lucy technically has a different origin from
Luke and
Lucas, but parents have used it as a feminine for them. And there are rare examples of other feminines like Lukette:

Jacklyn and
Jacklyn have been used as feminine forms of
Jack.
Though more rarely than
Noah and
Logan,
Troy has been used enough for girls to be noticeable, and feminines like Troyette exist:

The only two names on your list where it's really hard to find sure feminine forms of are
Ethan and
Liam. Etha was regularly used in the USA in the 19th and early 20th centuries, though, and may have been thought of by some parents as a feminine for
Ethan. Etana seems to be used in
Israel as a feminine form of Etan or
Eitan, the Hebrew forms of
Ethan.
Finally, I have found a reference to a social worker with the first name of Liama in Connecticut. In her case that may not have been created as a feminine for
Liam. But I am absolutely sure that some of the hundreds of thousands of Liams now being born around the world today will eventually have daughters or nieces named something like Liama, Liamette, Liamena, etc. after them.
