Houseplant Photo Identification? Also, Variegated Citrus?

I looked at a greenhouse today with a lot of citrus, and was told that a variegated citrus with pink-tinged blooms was a ‘Meyer’ lemon. Is anyone familiar with a variegated meyer lemon? I think the citrus I saw was probably a variegated pink lemon (it looked exactly like mine) but I wanted to be sure.

Anyone know for sure what these are?

Plant 1 close-up (This is the one I especially need identified, is it a bromeliad?):

Plant 1 overall view (the one in the bottom middle of the frame):

Plant 2 (anyone know what kind of bromeliad it is?):

Plant 3 (airplant/tillandsia?):

Thanks!
