Yes. A patent application may name multiple joint inventors when each person contributed to the conception of at least one claimed invention. The inventors do not need to contribute equally, work at the same time or location, or contribute to every claim.

A person is not an inventor merely because that person followed instructions, performed routine testing, managed a project, funded the work, or recognized the value of the invention. Conversely, a contributor should not be omitted simply because the contribution was limited to one claimed feature. Inventorship should be evaluated against the claims and revisited if the claims materially change during prosecution.
