No, they prohibit any (even modified) non-commertial redistribution of their textures. I don't like cgtextures due to tricky licensing terms. In simple words they prohibit using textures in open source games but allow using in commertial games.

May I use these textures in my Open Source (Creative Commons, GPL, etc) project?
No. These textures may not be used in Open-Source projects. The licenses are not compatible. Almost all Open-Source licenses allow redistribution of the materials, and redistribution is not allowed for these textures.
