I agree on the blanchetiana, the albo marginated has me stumped. I went out looking at some of my Aechmeas and and three have the middle green and white margin, Aechmea nudicaulis var. flavomarginata (looks the most like that one), A. Mend (gets a pink hue in bright light, but the leaves seem shiner than your friends), A. Felice (although that has wider leaves and no spines, clearly your friend's has spines). The bromeliad with the stripes look like it may have faded spots inside the leaves, then I would say some kind of Billbergia, the only Aechmea it looks similar too is, Aechmea fasciata Purpurea (mine has purple outside stripes, just like that one, and green inside, gets all purple in winter months fuller sun).
That's my best guess, Scott is good at IDing, maybe he'll know.
One way or the other, your friend got some very nice healthy bromeliads, with good offsets. Once they flower, easier to ID.
