The basic layout of the tags are as follows:

Soldier's Name Year of Birth
Unit
Place of residence or where served.

Thus the tag pictured at the top of the page could be interpreted as follows.

The former owner was gunner Max Rösch, born in 1919. He served with platoon No. 1 of light anti-aircraft battery No. 24. His home address at the time he served: 69 Peter Rotstrasse  in Basle.

However, there does tend to be a bit of variation from tag to tag.  For example:

The tag above follows the same general format, however, in this instance, the year of birth as well as the owners national insurance number are printed on the back of the tag (not shown.)  Also, the address has been seperated into to line.  Thus the tag may be translated as follows:

The rifle's owner was Charles Fahrion.  He served with the local defense company No.8.  At the time of his service, he lived at 26 Gemeindestrasse, in the city of Zurich, mail district 7.

On a side note Roger speculates

"Charles was possibly a man found not fit for service
with the regular army, but drafted into a local defense unit during the war.
These units were armed with older M 1896/11 or 1911 rifles."

A third tag provides us with still another slightly different format.

The above tag omits the date of birth altogether.  However, in this instance the name also includes a title.   It reads as follows:

"The former owner of the carabine was Pontonier (amphibious engineer) Willi Schenk. There is no numeral that tells us more about his age, but he served with engineer support company 1 of amphibious engineer battalion 2. He lived at the address of 7 Willi - Brüglingerstrasse  in Basle.
