I was wondering if two people can put their driver licenses in the same wallet. For example, could two spouses keep each of their licenses in the same wallet? Another example could be a parent and child having their licenses in a shared wallet. Would this violate laws that prevent people from carrying multiple licenses, or do laws against carrying multiple licenses apply only to carrying multiple licenses of the same person? And for purposes of clarification, we'll use Texas and Ohio as example jurisdictions, assuming such would be the same.
Two people, who agree to do so, can put their respective licenses in the same wallet. You can put twenty different people's licenses in a wallet (as a teacher leading a school field trip might, for example) as long as you have their permission to do so.
The prohibition on having multiple licenses is on having multiple licenses FOR THE SAME PERSON. It is not a prohibition on having multiple licenses for different people in the same place with the permission of the respective license holders.

There is no legal requirement to carry a licence so it depends on one's intent for having someone else's in their possession.
If they have it for convenience or as a favour etc then there is no offence. However, if their intent is "improper" or they do not have a "reasonable excuse" they may be commiting an offence under s.4 or s.6 of the Identity Documents Act 2010, respectively:
(1) It is an offence for a person (“P”) with an improper intention to have in P's possession or under P's control -
- (c) an identity document that relates to someone else.
(2) Each of the following is an improper intention -
(a) the intention of using the document for establishing personal information about P;
(b) the intention of allowing or inducing another to use it for establishing, ascertaining or verifying personal information about P or anyone else.
(4) A person guilty of an offence under this section is liable, on conviction on indictment, to imprisonment for a term not exceeding 10 years or a fine (or both).
(1) It is an offence for a person (“P”), without reasonable excuse, to have in P's possession or under P's control—
- (c) an identity document that relates to someone else,
(2) A person guilty of an offence under this section is liable—
(a) on conviction on indictment, to imprisonment for a term not exceeding 2 years or a fine (or both), or
(b) on summary conviction, to imprisonment for a term not exceeding the maximum period or a fine not exceeding the statutory maximum [i.e. 12 months] (or both).
As can be seen by the maximum sentences, s.4 is the more severe of the two. The burden of proof in s.6 is reversed and lies with the defendant to establish what is a reasonable excuse on the balance of probabilities.
There's also the possible offence of theft, but this appears to be off-topic judging by the tone of the question.
