Question Combining columns from multiple files to one file

I'm trying to combine colums from multiple file to a single file but having some issues, appreciate your help.

The filenames are the same except for the extension,

path1.m0
---------
a b c
d e f
g h i

path1.m1
---------
m n o
p q r
s t u

File names are path1.m[0 - 1]

The desired output file is path1.m and output is

a n
d q
g t

I can do this by the paste command

paste path1.m0 path1.m1 | awk '{print $1 $5}' > path1.m

The issue I'm having is that I've multiple files like
path2.m0
path2.m1

path3.m0
path4.m1

How do I set a variable to read all the path1.* and path2.* and path3* files and give the output files

path1.m
path2.m
path3.m


Thanks very much.

MBK_CATA_LIB(1)                                              MBK ENVIRONMENT VARIABLES                                             MBK_CATA_LIB(1)

NAME
MBK_CATA_LIB - define the mbk catalog directory SYNOPSYS
c-shell running setenv MBK_CATA_LIB path1:path2:path3:...:...:pathn ORIGIN
This software belongs to the ALLIANCE CAD SYSTEM developed by the ASIM team at LIP6 laboratory of Universite Pierre et Marie CURIE, in Paris, France. Web : http://asim.lip6.fr/recherche/alliance/ E-mail : alliance-users@asim.lip6.fr DESCRIPTION
MBK_CATA_LIB sets the directories that are to be searched thru for reading. When instanciating a cell for example, the first cell that is found with the given name is loaded in memory. The seaching mecanism first look in MBK_WORK_LIB(1), and then, in path1 thru pathn, in the order defined by the user when typing the setenv command. This directories are considered to be, from a mbk point of view, read only. The pathi arguments must be actually accessible pathes on your host machine. ERRORS
"mbk_fopen : can't open file 'unix_path/file.xx' thru directories : path1, ..., pathn" This occurs when either the unix path is irrelevent, or when the file doesn't exist. This can also be a unix right problem if the file is not accessible for reading, but this is seldom. EXAMPLE
setenv MBK_CATA_LIB ~fred/crechan/uom:/labo/sclib DIAGNOSTICS
Only the first path may be given with a '~', since the shell extents it only when seen first. SEE ALSO
mbk(3), genlib(1), MBK_WORK_LIB(1). BUG REPORT
This tool is under development at the ASIM department of the LIP6 laboratory. We need your feedback to improve documentation and tools. ASIM
