You cannot use the
uniq command for this because
uniq filters lines so that only unique ones (hence the name) remain. As all your lines are unique, because they all differ in some regards
uniq will not give you what you want.
awk might be able to give you the result you want once you can tell us what exactly the rules for your intended filtering are. I might be slow but i do not get it from a few example lines and two lines of expected output. Depending on these rules you might also take
sort into consideration as a probably helpful tool.
I hope this helps.

uniq(1) General Commands Manual uniq(1)
Name
uniq - report repeated lines in a file
Syntax
uniq [-udc[+n][-n]] [input[output]]
Description
The command reads the input file comparing adjacent lines. In the normal case, the second and succeeding copies of repeated lines are
removed; the remainder is written on the output file. Note that repeated lines must be adjacent in order to be found. For further infor-
mation, see
Options
The n arguments specify skipping an initial portion of each line in the comparison:
-n Skips specified number of fields. A field is defined as a string of non-space, non-tab characters separated by tabs and spaces from its
neighbors.
+n Skips specified number of characters in addition to fields. Fields are skipped before characters.
-c Displays number of repetitions, if any, for each line.
-d Displays only lines that were repeated.
-u Displays only unique (nonrepeated) lines.
If the -u flag is used, just the lines that are not repeated in the original file are output. The -d option specifies that one copy of
just the repeated lines is to be written. The normal mode output is the union of the -u and -d mode outputs.
The -c option supersedes -u and -d and generates an output report in default style but with each line preceded by a count of the number of
times it occurred.
